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 defining characteristic of an isosceles triangle?

• Two sides are equal.

• It has a right angle.

• All sides are equal.

• All angles are equal.

Why can we set up an equation for the sides of the triangle?

• Because the triangle is right-angled.

• Because the sides are marked as equal.

• Because the triangle is equilateral.

• Because the triangle is scalene.

What is the value of X after solving the equation?

• 2.5
