The law of sines , or sine rule,  states that the ratio of the length of a side to the sine of its corresponding opposite angle is constant, that is.
This ratio is equal to the diameter of the circumscribed circle of the given triangle. This triangle can be constructed by first constructing a circle of diameter 1, and inscribing in it two of the angles of the triangle.
The law of cosines , or cosine rule, connects the length of an unknown side of a triangle to the length of the other sides and the angle opposite to the unknown side.
The law of tangents , or tangent rule, can be used to find a side or an angle when two sides and an angle or two angles and a side are known.
It states that: . The triangle can be located on a plane or on a sphere. This problem often occurs in various trigonometric applications, such as geodesy , astronomy , construction , navigation etc.
Calculating the area T of a triangle is an elementary problem encountered often in many different situations.
The best known and simplest formula is:. The term "base" denotes any side, and "height" denotes the length of a perpendicular from the vertex opposite the base onto the line containing the base.
In CE Aryabhata , used this illustrated method in the Aryabhatiya section 2. Although simple, this formula is only useful if the height can be readily found, which is not always the case.
For example, the surveyor of a triangular field might find it relatively easy to measure the length of each side, but relatively difficult to construct a 'height'.
Various methods may be used in practice, depending on what is known about the triangle. The following is a selection of frequently used formulae for the area of a triangle.
The height of a triangle can be found through the application of trigonometry. Knowing ASA : .
The shape of the triangle is determined by the lengths of the sides. Therefore, the area can also be derived from the lengths of the sides.
By Heron's formula :. The area of a parallelogram embedded in a three-dimensional Euclidean space can be calculated using vectors. The area of parallelogram ABDC is then.
The area of triangle ABC is half of this,. The area of triangle ABC can also be expressed in terms of dot products as follows:.
In two-dimensional Euclidean space, expressing vector AB as a free vector in Cartesian space equal to x 1 , y 1 and AC as x 2 , y 2 , this can be rewritten as:.
If the points are labeled sequentially in the counterclockwise direction, the above determinant expressions are positive and the absolute value signs can be omitted.
The area within any closed curve, such as a triangle, is given by the line integral around the curve of the algebraic or signed distance of a point on the curve from an arbitrary oriented straight line L.
Points to the right of L as oriented are taken to be at negative distance from L , while the weight for the integral is taken to be the component of arc length parallel to L rather than arc length itself.
This method is well suited to computation of the area of an arbitrary polygon. The sign of the area is an overall indicator of the direction of traversal, with negative area indicating counterclockwise traversal.
The area of a triangle then falls out as the case of a polygon with three sides. While the line integral method has in common with other coordinate-based methods the arbitrary choice of a coordinate system, unlike the others it makes no arbitrary choice of vertex of the triangle as origin or of side as base.
Furthermore, the choice of coordinate system defined by L commits to only two degrees of freedom rather than the usual three, since the weight is a local distance e.
With this formulation negative area indicates clockwise traversal, which should be kept in mind when mixing polar and cartesian coordinates. Three formulas have the same structure as Heron's formula but are expressed in terms of different variables.
See Pick's theorem for a technique for finding the area of any arbitrary lattice polygon one drawn on a grid with vertically and horizontally adjacent lattice points at equal distances, and with vertices on lattice points.
The area can also be expressed as . In , Baker  gave a collection of over a hundred distinct area formulas for the triangle. These include:.
Other upper bounds on the area T are given by  : p. There are infinitely many lines that bisect the area of a triangle. Three other area bisectors are parallel to the triangle's sides.
Any line through a triangle that splits both the triangle's area and its perimeter in half goes through the triangle's incenter.
There can be one, two, or three of these for any given triangle. The medians and the sides are related by  : p. For angle A opposite side a , the length of the internal angle bisector is given by .
The product of two sides of a triangle equals the altitude to the third side times the diameter D of the circumcircle:  : p.
Suppose two adjacent but non-overlapping triangles share the same side of length f and share the same circumcircle, so that the side of length f is a chord of the circumcircle and the triangles have side lengths a , b , f and c , d , f , with the two triangles together forming a cyclic quadrilateral with side lengths in sequence a , b , c , d.
Each vertex in a triangle forms an angle. As we know that there are three vertices in a triangle, and each vertex forms an angle in a triangle. Hence, a triangle has three angles, and each angle of a triangle meets at a common point vertex.
In simple words, if an angle lies in the interior of a triangle, then it is called an interior angle. A triangle has three interior angles.
The sum of all interior angles of the triangle is equal to degrees. Click here to turn the theme off. Or come to our Facebook page and tell us all about it.
Triangles is a very simple game. The objective is to make as many triangles as possible, by drawing lines from one dot to another.
And that's it. The shortest rule section I've ever written : If you're playing with a mouse you just click on one dot and drag the mouse over to the dot you want to connect to.
On a touchscreen you just touch a dot with your finger and drag it over to the other dot. This online version of Triangles was made by me, Einar Egilsson.
Over there on the left is my current Facebook profile picture. This is a game I played when I was a kid in Iceland, with pen and paper. You just put a bunch of random dots on the paper and then start drawing lines.
I had forgotten all about it until I saw on Snapchat that a friend was playing it with her kids. I played it a few times with my wife and kids and started thinking it could be a nice little game to make for the site.
This is the first game I've made for the site that has some dynamic graphics. I've been wanting to create some more puzzle games, not just card games and this is a nice start.
Also it was a good opportunity to learn a bit about html5 canvas rendering, and freshen up on my geometry which apparently I'm terrible at!
