Question

Given ABC where AC = 7.12 cm, BC = 7.12 cm, and AB = 7.12 cm, then the mZB =
С

Answer 1

The measure of m∠B = 60°

Explanation:

The given parameters are;

The length of the sides of ΔABC includes;

Side AC = 7.12 cm

Side BC = 7.12 cm

Side AB = 7.12 cm

Therefore, given that all the sides of the triangle are equal, we have that the triangle is an equilateral triangle

The measure of the each interior angle of an equilateral triangle = 60°, by definition of equilateral triangle

∴ The measure of m∠B = 60°.
