Understanding Angles

Why are angles considered crucial in construction and design?

• For aesthetic appeal

• To ensure structures are stable

• For calculating area only

• To make designs more complex

What defines an acute angle?

• An angle of 180 degrees

• An angle more than 90 degrees but less than 180 degrees

• An angle exactly 90 degrees

• An angle less than 90 degrees

Where can you find a right angle in everyday life?

• A slice of pizza

• The letter 'L'

• The blades of a windmill

• The slanting lines of the letter 'B'

Identify an example of an obtuse angle.

• The corner of a square

• The angle between two adjacent fingers

• The angles between the blades of a windmill

• The angle in a slice of pizza

What is the measure of a straight angle?

• Less than 90 degrees

• 360 degrees

• 90 degrees

• 180 degrees

What range of degrees does a reflex angle cover?

• Exactly 360 degrees

• 180 to 360 degrees

• 90 to 180 degrees

• 0 to 90 degrees

Which angle is formed when a ray completes one full rotation?

• Full or complete angle
