Question

Classify the following triangle, Check all that apply.

A. Isosceles
B. Obtuse
C. Acute
D. Right
E. Equilateral
F. Scalene

Answer 1

A D

Explanation:

the box in the corner signifies a right angle, so this is a right triangle (D).

the 2 dashes mean that 2 of the sides are equal, but not all three, since the 3rd side doesn't have a dash. this means the triangle is an isosceles triangle (A).
