Question

for each triangle, check all that apply.
triangle a
14
14
14
scalene isosceles equilateral
← previous

Explanation:

Step1: Recall triangle types

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

Step2: Analyze Triangle A

Triangle A has all three sides equal to 14. So it satisfies Isosceles (since at least two equal, here all three) and Equilateral (all three equal). It does not satisfy Scalene (as sides are not all different).

Answer:

Isosceles, Equilateral (check the boxes for Isosceles and Equilateral)
