Angle Sum Property QuizOnline version

Test the triangle angle sum.

by Yuri Buitron - Julieth Narvaez _ Grupo 92
1

What is the sum of the interior angles of a triangle?

2

If two angles are 40° and 50°, what is the third angle?

3

If two angles are 60° and 60°, the third is:

4

True or False: All triangles have a sum of 180°.

5

If one angle is 90° and another is 30°, the third is:

6

70° + 50° + ? = 180°

7

If a triangle has angles 100° and 40°, the third is:

8

If all angles are equal, each one is:

9

30° + 80° + ? = 180°

10

If one angle is 120°, the other two add up to:

Explicación

The interior angles of any triangle sum to 180°.

Sum of angles in a triangle is 180°, so 40°+50°=90° for the third.

60°+60°+60°=180°.

All Euclidean triangles sum to 180°.

180° total minus 90° and 30° equals 60°.

60° completes the sum to 180°.

Sum of angles is 180°, so third = 180-140 = 40°.

Equal angles in a triangle divide 180° by 3.

Third angle must complete 180° total.

180° minus 120° equals 60°.
