Door Opening (Identify measurements of special types of angles (e.g. right angles, straight angles, zero angles, acute a

The video tutorial uses a door to explain different types of angles, including right, straight, and zero degree angles. It demonstrates how to measure angles using a protractor and discusses the properties of acute and obtuse angles. The lesson emphasizes understanding angle measurements and their classifications.

What type of angle is formed when a door is opened at a right angle?

• Right angle

• Acute angle

• Straight angle

• Obtuse angle

When a door is fully opened to form a straight line, what is the angle called?

• Acute angle

• Straight angle

• Right angle

• Zero degree angle

What is the measure of a straight angle?

• 90 degrees

• 45 degrees

• 0 degrees

• 180 degrees

What is the measure of an angle when the door is completely closed?

• 90 degrees

• 0 degrees

• 180 degrees

• 45 degrees

What is the measure of a right angle?

• 45 degrees
