Match the angle type with its corresponding degree measure range:

Acute Angle = Between 0° and 90° Obtuse Angle = Between 90° and 180° Reflex Angle = Between 180° and 360° Straight Angle = Exactly 180°

Match the angle pair with its corresponding sum:

Complementary Angles = 90° Supplementary Angles = 180° Vertical Angles = Equal Adjacent Angles = Varies

Match the description with the term it defines:

Positive Angle = Measured counterclockwise from the base Negative Angle = Measured clockwise from the base Linear Pair = Adjacent angles forming a straight line Transversal = A line intersecting two or more lines

Match the angle with its description:

Right Angle = Exactly 90 degrees Obtuse Angle = Greater than 90 degrees but less than 180 degrees Acute Angle = Less than 90 degrees Reflex Angle = Greater than 180 degrees but less than 360 degrees Signup and view all the answers

Match each angle type with its description:

Reflex Angle = An angle greater than 180° but less than 360° Full Rotation = An angle equal to 360° Acute Angle = An angle less than 90° Obtuse Angle = An angle more than 90° but less than 180° Signup and view all the answers
