The isosceles triangle is a polygon with three sides, two of them, of equal size. The polygon is a closed plane
figure composed by a non specified number of straight line segments that join in pairs at their endpoints.
For a triangle, the sum of two sides must be always greater than the third.
A corner of a triangle is known as a vertex. The opposite side is that side which is opposite to a given vertex. The adjacent side is that share the same vertex.
The angle is the opening formed by two line segments, connected together at their extremities. The angles may be measured in degrees and radians. The most common unit of measure is degrees. The sum of the interior angles is 180 degrees.
The radian is an angular measure of an arc whose value corresponds to the radius of the circle that contains the arc.
For the conversion purposes, 1 degree is equals Π /180 radians and 1 radian equals 180/ Π degrees.
A triangle always has three different heights depending on the three sides of the triangles that you choose to be the baseline.
