Understand the Relationship Between Exterior Angles

This video tutorial covers the concept of exterior angles in triangles, explaining how they relate to the interior angles. It reviews the basic properties of triangle angles, introduces the exterior angle theorem, and demonstrates how to apply this theorem to solve problems. The tutorial concludes with a practical application, showing how to use exterior angles in real-world scenarios, such as designing a skateboard ramp.

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

• 360 degrees

• 180 degrees

• 90 degrees

• 270 degrees

How is an exterior angle of a triangle related to its interior angles?

• It is equal to the difference between the two adjacent interior angles.

• It is equal to the sum of the two adjacent interior angles.

• It is equal to the sum of the two non-adjacent interior angles.

• It is equal to the difference between the two non-adjacent interior angles.

If an exterior angle of a triangle is 106 degrees, what is the measure of the adjacent interior angle?

• 90 degrees
