Triangle Angles and Their Properties

This video tutorial covers the properties of interior and exterior angles of triangles. It explains how to use equations to find missing angle measures and solve real-life problems. The tutorial demonstrates the sum of interior angles in a triangle and the relationship between exterior angles and non-adjacent interior angles. A practical example involving the Bermuda Triangle is used to apply these concepts.

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

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

If two angles of a triangle are 32 degrees and 48 degrees, what is the measure of the third angle?

• 100 degrees

• 90 degrees

• 80 degrees

• 60 degrees

In a triangle with angles x, x+28, and 90 degrees, what is the value of x?

• 31 degrees

• 28 degrees

• 45 degrees

• 60 degrees

What is the relationship between an exterior angle and the non-adjacent interior angles of a triangle?

• The exterior angle is equal to the product of the two non-adjacent interior angles.

• The exterior angle is equal to the average of the two non-adjacent interior angles.

• The exterior angle is equal to the difference of the two non-adjacent interior angles.

• The exterior angle is equal to the sum of the two non-adjacent interior angles.

If an exterior angle of a triangle is 108 degrees, what is the sum of the two non-adjacent interior angles?

• 108 degrees

• 72 degrees

• 180 degrees

• 90 degrees

• 80 degrees

• 75 degrees

• 85 degrees

How do you find the measure of an exterior angle in a triangle?

• By adding the two adjacent interior angles.

• By subtracting the two adjacent interior angles.

• By adding the two non-adjacent interior angles.

• By subtracting the two non-adjacent interior angles.
