Adding Angles and Angle Properties

The video tutorial explains how to find the measure of an angle by adding smaller angles. It starts by identifying two angles, 45° and 65°, and demonstrates that angle measures are additive. By adding these two angles, the total angle measure is calculated to be 110°. The tutorial emphasizes the simplicity of finding the total angle by summing smaller angles.

What are the two angles mentioned in the problem that need to be added?

• 30° and 60°

• 45° and 65°

• 50° and 70°

• 40° and 60°

What property of angles allows us to add smaller angles to find a larger angle?

• Additive property

• Divisive property

• Subtractive property

• Multiplicative property

How do you find the measure of the entire angle when given smaller angles?

• Subtract the smaller angles

• Multiply the smaller angles

• Add the smaller angles

• Divide the smaller angles

What is the total measure of the angle when you add 45° and 65°?

• 120°

• 100°

• 90°

• 110°

What is the final step to determine the size of a larger angle from smaller angles?

• Add the two smaller angles

• Subtract the smaller angles from each other

• Multiply the smaller angles

• Divide the smaller angles
