Question

Which set of angle measurements could be the three interior angles that form a triangle? A: 22°,61°,97° B: 45°,45°,60° C: 39°,42°,37° D:60°,110°,30°

Answer 1

A

Explanation:

The interior angle measurements of a triangle must all add up to 180 degrees, so to find out which of these would work, we just have to add them.

A: 22, 61, 97

22 + 61 + 97 = 180

These angles add up to 180 degrees, so they work!

B: 45, 45, 60

45 + 45 + 60 = 150

These angles do not add up to 180 degrees, so they don't work.

C: 39, 42, 37

39 + 42 + 37 = 118

These angles do not add up to 180 degrees, so they don't work.

D: 60, 110, 30

60 + 110 + 30 = 200

These angles do not add up to 180 degrees, so they don't work.
