Applying the interior sum theorem to determine the missing angles of two

The video tutorial explains how to determine missing angles in triangles using the triangle angle sum theorem and angle relationships. It covers solving for missing angles in right triangles and using linear pairs to find two missing angles. The tutorial concludes with verifying the solutions to ensure accuracy.

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

• 360 degrees

• 180 degrees

• 90 degrees

• 270 degrees

If two angles of a triangle are 27 degrees and 90 degrees, what is the measure of the third angle?

• 63 degrees

• 53 degrees

• 73 degrees

• 83 degrees

What is a linear pair of angles?

• Two angles that are equal

• Two angles that add up to 90 degrees

• Two angles that are complementary

• Two angles that add up to 180 degrees

If angle 3 and 27 degrees form a linear pair, what is the measure of angle 3?

• 153 degrees

• 127 degrees

• 147 degrees

• 133 degrees

How can you verify that the angles of a triangle are calculated correctly?

• By checking if the sum is 270 degrees

• By checking if the sum is 180 degrees

• By checking if the sum is 360 degrees

• By checking if the sum is 90 degrees
