How to determine the coterminal acute positive angle

The video tutorial explains how to find coterminal angles, focusing on the example of 410 degrees. It discusses the concept of revolutions, specifically 360 degrees, and how subtracting this from a given angle can help find a positive acute coterminal angle. The tutorial emphasizes that coterminal angles share the same terminal side, even if their measures differ.

What is the primary method to find a coterminal angle for a given angle?

• Add or subtract 90 degrees

• Add or subtract 45 degrees

• Add or subtract 360 degrees

• Add or subtract 180 degrees

Why is 360 degrees used when finding coterminal angles?

• It is the sum of two right angles

• It represents a half circle

• It represents a full circle or revolution

• It is the smallest angle possible

What is the result of subtracting 360 degrees from 410 degrees?

• 30 degrees

• 60 degrees

• 50 degrees

• 40 degrees

What is the definition of coterminal angles?

• Angles that are both obtuse

• Angles that have the same measure

• Angles that have the same initial and terminal side

• Angles that are both acute

How can you find a positive acute angle that is coterminal with a given angle?

• Subtract 360 degrees

• Add 360 degrees

• Subtract 180 degrees

• Add 180 degrees
