What is the length of the sides of an isosceles triangle?

The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.

How do you find the lengths of the legs of an isoceles triangle when given the angle?

With only the angle provided, you cannot find the lengths of the sides. The reason for this is that the isosceles triangle can be scaled up or down. If you had an isosceles triangle with a vertex of, say, 20 degrees, the other two angles would be 80 degrees each. This triangle could be constructed with the pair of congruent sides 10 centimeters long, 10 feet long, 10 miles long, or any length, and it would still have the same angles in its construction. Angles alone are insufficient to discover the length of the sides of an isosceles triangle.
