the main property of isosceles triangles is their two congruent sides. In addition, all isosceles triangles also have congruent base angles.



This property holds true for all isosceles triangles, no matter which direction their apexes point.



If we know the measure of either of the base angles, then we can determine the measure of the third (apex) angle. Since the angles of a triangle add up to 180 degrees, the third angle is 180 minus two times a base angle, making the formula for the measure of an isosceles triangle's apex angle:

A = 180 - 2b

Where A is the apex measure and b is the measure of one base angle.

So if a base angle in an isosceles triangle measured 58 degrees, we could plug that into our formula to determine the measure of the apex angle:

A = 180 - (2 * 58)

A = 180 - 116

A = 64

The measure of the triangle's apex angle is 64 degrees.
