Question

Select three angle measures that can represent three angles of a triangle. Write the measures in box a

100° 80° 30° 90° 70° 10°

Answer 1

All 3 interior angles of a triangle must add up to 180.

The following sets of angles can be used to create a triangle:

10, 80, 90
10 + 80 + 90 = 180

10, 70, 100
10 + 70 + 100 = 180

30, 70, 80
30 + 70 + 80 = 180
