Isosceles Triangle -- from Wolfram MathWorld
An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal.

Triangles - Equilateral, Isosceles and Scalene
Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:
Isosceles triangle - Wikipedia
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
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).
Isosceles Triangle Unit
Notes: 1) After independently coming up with this unit I discovered that Jeannine Mosely came up with it as well. 2) The finished unit in step 5 can be used for constructing both the lesser and the greater stellated dodecahedra.
