Question

An isosceles triangle has an angle that measures 120°. Which other angles could be in that isosceles triangle? Choose all that apply.

Answer 1

they will be both 30°.

Explanation:

in an isosceles triangle measure of two angles are same

if one angle of an isosceles triangle is 120°

and the other two angles are equal then

take the equal angles be x

so,

• x + x + 120° = 180°
• 2x = 180° - 120°
• x = 60° / 2
• x = 30°
