Which set of angles could NOT be the measure of the interior angles of a triangle?

Question

HINT - All angles must add up to equal 180 degrees

Answer 1

90°, 50°, 40°.

Because if you add them up:

90° + 50° + 40° = 180°

These angles could be the measures of the interior angles of a triangle.

Any set of angles that add up to more or less than 180 degrees could not be the measure of the interior angles of a triangle.
