Question

Find the angle measures in the isosceles triangle.

Possible answers:
A) f = 18°
B) f = 118°
C) f = 68°
D) f = 11.7°

Answer 1

It should be C because and isosceles triangles mean that two angles will equal and the total of all three angles should be 180. If the angle that is not the base of the isosceles triangle u need to subtract 180 from the vertex angle and then divide the difference by 2 to be the answer.

Answer 2

C, 68°

Explanation:

Since all triangle have an interior angle measure of 180° and isosceles triangles have two congruent angles, all you need to do to find m∠f is to subtract 44° from 180° and then divide by two.

180°-44°=136°

136°/2=68°
