What is true of triangle FGH?

a.It is a right triangle.
b.It is an obtuse triangle.
c.It has exactly 2 congruent sides.
d.It has exactly 3 congruent sides.

Answer 1

D.It has exactly 3 congruent sides.

Explanation:

Answer 2

d. It has exactly 3 congruent sides. This is because this is an equilateral triangle whose sides are congruent.

angle GFH= 180 - (90+30) = 60
angle GHF= 180 - (90+30) = 60
angle FGH= 30 + 30 = 60
