Question

triangle c
7
4
4
scalene isosceles equilateral

Explanation:

Step1: Recall triangle types

• Scalene: All sides different.
• Isosceles: At least two sides equal.
• Equilateral: All three sides equal.

Step2: Analyze Triangle C's sides

Triangle C has sides 4, 4, 7. Two sides (4, 4) are equal.

Step3: Match to triangle type

Since two sides are equal, it's isosceles. Scalene (all different) and equilateral (all equal) don't apply.

Answer:

$\boldsymbol{\text{Isosceles}}$ (and check the box for Isosceles)
