Determine the measure of each side of a isosceles triangle

The video tutorial explains how to solve a problem involving an isosceles triangle. It begins by identifying the triangle's properties and setting up an equation based on the equality of two sides. The instructor then solves for the variable X and uses it to calculate the lengths of the triangle's sides. The tutorial concludes by confirming the equality of the triangle's angles.

What is the relationship between the two equal sides of the triangle?

What conclusion can be drawn about the angles of the triangle?
