What is the definition of an acute angle?

• An angle that is exactly 90°

• An angle that is 0° < x < 90°

• An angle that is 90° < x < 180°

• An angle that is 180°

Fill in the blank: A right angle measures ______ degrees.

• 90

• 45

• 60

• 120

Which of the following is a straight angle?

• 0°

• 90°

• 180°

• 360°

What is a linear pair?

• Two angles that are congruent

• Two angles that form a line (supplementary)

• Two angles that are vertical

• Two angles that are adjacent

Vertical angles are:

• Adjacent angles

• Angles on the same side of a transversal

• Angles opposite across an 'X' (congruent)

• Supplementary angles

Match the following angle numbers to their groups:

Groups:

(a) Corresponding Angles

,

(b) Same Side Interior

,

(c) Alternate Interior

,

(d) Alternate Exterior

Corresponding angles are:

• On opposite sides of the transversal

• On the same side of the transversal in corresponding positions

• Adjacent to each other

• Supplementary angles

Alternate Interior Angles are:

• Non-adjacent interior angles on opposite sides of the transversal

• Adjacent interior angles on the same side of the transversal

• Exterior angles on opposite sides of the transversal

• Angles in corresponding positions

Same-side Interior Angles are:

• Interior angles on the same side of the transversal

• Interior angles on opposite sides of the transversal

• Exterior angles on the same side of the transversal

• Angles in corresponding positions

Alternate Exterior Angles are:

• Interior angles on the same side of the transversal

• Exterior angles on opposite sides of the transversal

• Angles in corresponding positions

• Adjacent angles
