How to construct (draw) a triangle given three sides ...
This page shows how to construct a triangle given the length of all three sides, with compass and straightedge or ruler. It works by first copying one of the line segments to form one side of the triangle. Then it finds the third vertex from where two arcs intersect at the given distance from each end of it. A Euclidean construction.
Triangle - Wikipedia
A triangle is a polygon with three edges and three vertices.It is one of the basic shapes in geometry.A triangle with vertices A, B, and C is denoted .. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space).In other words, there is only one plane that contains that triangle, and every ...
Isosceles Triangle -- from Wolfram MathWorld
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length .This property is equivalent to two angles of the triangle being equal.
