Question

Which sets of measurements could be the interior angle measures of a triangle?

Select each correct answer.

Question 2 options:

10°, 10°, 160°

15°, 75°, 90°

20°, 80°, 100°

35°, 35°, 105°

60°, 60°, 60°

Answer 1

The sum of all the three interior angles of a triangle are 180 degrees. This does not depend on the positioning of the three sides. The sides can be positioned in any way, but the sum must be 180 degrees.

So, the best possible sets of measurements that could be the interior angle measures of a triangle are : 15°, 75°, 90° And 60°, 60°, 60°
