Geometry: Measurement of Angles (Level 2 of 9)

This video tutorial covers the classification of angles by size in geometry. It explains six types of angles: acute, right, obtuse, straight, reflex, and full angles. The tutorial provides detailed descriptions and characteristics of each angle type, including their measures and visual representations. It also discusses the concept of perpendicular lines in relation to right angles and highlights the importance of recognizing common angles in geometry courses.

What is the range of degrees for an acute angle?

• 0 to 90 degrees

• 90 degrees only

• 180 to 360 degrees

• 90 to 180 degrees

Which symbol is used to indicate a right angle?

• A square corner

• A curved arrow

• A circle

• A straight line

What is the relationship between perpendicular lines?

• They form an acute angle

• They form a right angle

• They form a straight angle

• They form an obtuse angle

What is the measure of a straight angle?

• 360 degrees

• 270 degrees

• 180 degrees

• 90 degrees

How is a reflex angle typically denoted?

• With a curved arrow

• With a straight line

• With a circle

• With a square corner

What is the measure of a full angle?

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

Which of the following is NOT a common angle to recognize?

• 45 degrees

• 135 degrees

• 225 degrees

• 400 degrees
