Lines and Angles Quiz

Explain what parallel lines are and provide an example.

• Parallel lines are lines that form a right angle. Like the edges of a board

• Parallel lines are lines that are curved and never meet. like the movement of hands on a clock

• Parallel lines are lines that intersect at a single point. They are like an x, which intersect at a common point

• Parallel lines are lines that are staight and never meet. An example of parallel lines is the sides of a rectangle.

If angle A is 70 degrees, what is the measure of its supplementary angle?

(Hint: 70 + _ = 180 degrees)

• 90 degrees

• 120 degrees

• 110 degrees

• 100 degrees

Define linear pairs of angles

• Two angles measuring 60 degrees and 120 degrees

• An example of linear pairs of angles is two angles measuring 90 degrees and 90 degrees, which add up to 180 degrees.

• Two angles measuring 45 degrees and 45 degrees

• Two angles measuring 90 degrees and 90 degrees, which add up to 270 degrees

Construct an angle of 45 degrees using a protractor.

• Fold the paper to create a 45-degree angle.

• Estimate the angle visually without a protractor.

• Use a protractor to measure and mark a 45-degree angle.

• Use a compass to draw a 45-degree angle.

How many degrees are in a straight angle?

• 90 degrees

• 270 degrees

• 180 degrees

• 360 degrees

List the different types of angles.

• Complementary angles

• Reflex angles

• Vertical angles

• Acute angles, Right angles, Obtuse angles, Straight angles

Construct an angle of 90 degrees using a protractor.

• Draw a triangle with all angles measuring 90 degrees.

• Measure the length of a side of a square to be 90 degrees.

• Construct a line at 90 degrees to the base line using the protractor.

• Use the protractor to draw a circle with a radius of 90 units.
