(Note that since the question explicitly tells you that four of the five answers are possible lengths, it cannot be possible to determine the length of the base by some formula!). Having proven the Base Angles Theorem for isosceles triangles using triangle congruency, we know that in an isosceles triangle the legs are equal and the base angles are congruent.

An isosceles triangle looks like this: As you can see in the image uploaded above, the isosceles triangle has a couple of sides with equal length a. b is the base and h is the height of the isosceles triangle. In Euclidean geometry, the base angles can not be obtuse (greater than 90°) or right (equal to 90°) because their measures would sum to at least 180°, the total of all angles in any Euclidean triangle.

Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Given the base and angles of an isosceles triangle, how to find length of the two sides? To mathematically prove this, we need to introduce a median line, a line constructed from an interior angle to the midpoint of the opposite side. This forms two congruent right triangles that can be solved using Pythagoras' Theorem as shown below. The length of the base, called the hypotenuse of the triangle, is times the length of its leg. The base angles of an isosceles triangle are always equal. Draw all points X such that true that BCX triangle is an isosceles and triangle ABX is isosceles with the base AB.
