One angle of an isosceles triangle is 28°. What are the other 2 angles? (Choose all that apply.)

76 degrees and 76 degrees
116 degrees and 116 degrees
28 degrees and 152 degrees
28 degrees and 124 degrees

In an isosceles triangle, the base angles (the angles opposite the equal sides) are congruent.

Since one angle of the isosceles triangle is 28 degrees, the other two angles are also 28 degrees each.

Therefore, the correct answer is:

28 degrees and 28 degrees

To solve this question, we need to understand the properties of an isosceles triangle.

In an isosceles triangle, two sides are congruent (equal in length) and two angles are congruent (equal in measure).

Since we know that one angle of the isosceles triangle is 28 degrees, we can conclude that the other two angles must be congruent to each other.

To find the measure of the other two angles, we can subtract 28 degrees from 180 degrees (the sum of all angles in a triangle).

180 degrees - 28 degrees = 152 degrees

Therefore, the other two angles of the isosceles triangle are 152 degrees each.

Therefore, the correct answer is:
- 28 degrees and 152 degrees

76 degrees and 76 degrees

28 degrees and 124 degrees
