Question

a triangle has angle measurements of 56°, 56°, and 68°. what kind of triangle is it?
equilateral
isosceles but not equilateral
scalene

Explanation:

Step1: Recall triangle type definitions

• Equilateral: All angles equal ($60^\circ$ each).
• Isosceles: At least two angles equal.
• Scalene: All angles different.

Step2: Analyze given angles

Given angles: $56^\circ$, $56^\circ$, $68^\circ$. Two angles ($56^\circ$) are equal, so not scalene. Angles aren't all equal (not $60^\circ$), so not equilateral. Thus, it's isosceles but not equilateral.

Answer:

B. isosceles but not equilateral
