Question

For each set of three measures, determine if they can be angle measures of a triangle.

Answer 1

The sum of the angles in the triangle must be equals to 180 degrees for it to be the angle measure of a triangle.

Angles in a triangle

The sum of angles in a triangle is equals to 180 degrees.

Therefore, adding up the three angles in a triangle must be equals to 180 degrees.

Hence,

42 + 34 + 56 = 132 degrees

This does not form a triangle.

35 + 80 + 65 = 180 degrees

This can be the angle measure of a triangle.

15 + 51 + 24 = 90 degrees

This cannot be the angle measure of a triangle.

18 + 42 + 120  = 180

This can be the angle measure of a triangle.
