Two sides of a triangle each measure 8 in Maria says the triangle must be isosceles is Mario correct explain A Yes an isosceles triangle has at least two sides that have equal measures B Yes the third side could measure 9 in and the triangle would be equilateral

Answer 1

A is the correct answer.

An isosceles triangle is defined as a triangle that has at least two sides of equal length. Since Maria has two sides measuring 8 inches, it meets the criteria for being an isosceles triangle regardless of the length of the third side.

However, B is incorrect. An equilateral triangle has all sides equal, which means that if the third side measured 9 inches, the triangle would not be equilateral.

Therefore, the correct response is: A: Yes, an isosceles triangle has at least two sides that have equal measures.
