Geometry Lines and Angles

Identify the type of angle: An angle that measures exactly 90 degrees.

• Obtuse angle

• Right angle

• Straight angle

• Acute angle

Identify the type of angle: An angle that measures more than 90 degrees but less than 180 degrees.

• Obtuse angle

• Straight angle

• Acute angle

• Right angle

Use a protractor to measure the angle: “Draw an angle that measures 45 degrees and measure it using a protractor.”

• 45 degrees

• 30 degrees

• 90 degrees

• 60 degrees

Use a protractor to measure the angle: “Draw an angle that measures 120 degrees and measure it using a protractor.”

• 60 degrees

• 120 degrees

• 180 degrees

• 90 degrees

What type of lines intersect to form a right angle?

• Parallel lines

• Perpendicular lines

• Intersecting lines

• Skew lines

a line that joins 2 vertices

• angle

• side

• vertex

What type of angle is less than 90 degrees?

• Right angle

• Acute angle

Identify the pair of lines that are parallel: AB and CD

• AC and BD

• XY and ZW

• EF and GH

• AB and CD

Identify the pair of lines that are perpendicular: EF and GH

• LM and NO

• EF and JK

• EF and GH

• AB and CD

Draw a line segment.

• Use a protractor to draw a curved line

• Draw a line segment by freehand without any tools

• Use a compass to draw a circle instead of a line segment

• Use a ruler or straight edge to draw a straight line between two points
