Question

Describe and correct the error made in finding BC in the diagram Shown. (Hint: It is an Isosceles triangle)

Answer 1

BC = 5

Explanation:

Since it is an isosceles, it is the base angles that are equal

Since the base angles are equal, then the sides facing these angles are equal

Mathematically, what we are supposed to have as equals should be AB and BC since they are the sides facing the base angles

Thus, BC should be 5
