What symbol is commonly used to indicate parallel lines?

• A circle

• Dots

• Arrows

• A square

What type of angles add up to 180 degrees?

• Supplementary angles

• Vertical angles

• Corresponding angles

• Congruent angles

Which angles are always congruent?

• Alternate interior angles

• Vertical angles

• Alternate exterior angles

• Supplementary angles

What is a transversal?

• A line parallel to one and perpendicular to another

• A line intersecting two lines in the same plane at two different points

• A line that divides an angle into two equal parts

• A line that intersects two or more lines

What are corresponding angles?

• Angles that are opposite to each other

• Angles that add up to 180 degrees

• Angles in the same position on parallel lines cut by a transversal

• Angles that are both inside the parallel lines and on opposite sides of the transversal

What are alternate interior angles?

• Angles on opposite sides of a transversal and outside the two lines

• Angles on the same side of a transversal and outside the two lines

• Angles on the same side of a transversal and inside the two lines

• Angles on opposite sides of a transversal and inside the two lines

If angle 2 is 120 degrees, what is the measure of angle 4?

• 120 degrees

• 180 degrees

• 90 degrees

• 60 degrees

If angle 1 is 60 degrees, what is the measure of angle 5?

• 120 degrees

• 90 degrees

• 60 degrees

• 180 degrees

What property do vertical angles have?

• They are always congruent

• They add up to 180 degrees

• They are supplementary

• They are adjacent to each other
