Question

What type of triangle is pictured in the following figure?

A. isosceles
B. right
C. equilateral
D. scalene

Answer 1

A. Isosceles

Explanation:

Since two angles are congruent, then the opposite sides are congruent. The two congruent angles measure 70 and 70.

70 + 70 = 140

180 - 140 = 40

The third angle measures 40. The third side is not congruent to the other two, so the triangle is isosceles but not equilateral.

Answer 2

This is an isosceles triangle. The angles in the legs are congruent therefore making the legs congruent as well. Hope this helps!
