Types and Measures of Angles

The video tutorial covers the estimation of angles, including acute, obtuse, and reflex angles. It begins with a review of basic angle types and their degrees, such as right angles and straight lines. The tutorial then demonstrates how to estimate angles using visual cues and a protractor, providing examples for each type of angle. The video emphasizes the importance of understanding angle measurements to make accurate estimations.

What is the degree measure of a right angle?

• 45°

• 360°

• 90°

• 180°

Which type of angle is greater than 90° but less than 180°?

• Right

• Obtuse

• Reflex

• Acute

How many degrees are in a full turn?

• 360°

• 270°

• 180°

• 90°

If an angle is less than a right angle, what could be its approximate measure?

• 180°

• 270°

• 100°

• 45°

What tool is used to measure angles accurately?

• Protractor

• Compass

• Ruler

• Calculator

If an angle is 45°, what type of angle is it?

• Reflex

• Obtuse

• Acute

What is the measure of an angle that is half of a right angle?

• 360°

• 180°

• 90°

• 45°

An angle slightly larger than a right angle is estimated to be around:

• 45°

• 180°

• 90°

• 100°

What is the degree measure of a straight line?

• 90°

• 180°
