Unit 3 - Parallel Line and Transversals

What is the angle relationship between \( \angle6 \) and \( \angle7 \)?

• Adjacent Angles, which are supplementary.

• Complementary Angles, which add up to 90 degrees.

• Vertical Angles, which are equal.

• Corresponding Angles, which are equal.

What are Vertical Angles?

• Angles that are adjacent to each other when two lines cross.

• Angles that are opposite each other when two lines cross. They are always equal.

• Angles that are supplementary to each other.

• Angles that are complementary to each other.

Define Corresponding Angles.

• Pairs of angles that are equal in measure.

• Pairs of angles that are in the same relative position at each intersection where a straight line crosses two others.

• Pairs of angles that are supplementary to each other.

• Pairs of angles that are adjacent to each other.

Classify the marked angles and solve for x: \( x = 12 \) degrees.

• Corresponding Angles

• Alternate Interior Angles

• Consecutive Interior Angles

• Vertical Angles

Find the measure of angle 1 if it is 44°.

• 42°

• 44°

• 46°

• 40°

Solve for y if y = 10.

• The value of y is 5.

• The value of y is 10.

• The value of y is 15.

• The value of y is 20.

If \( \angle3 = 60° \), what is \( \angle4 \) if they are Same Side Interior Angles?

• \( \angle4 = 90° \)

• \( \angle4 = 120° \)

• \( \angle4 = 150° \)

• \( \angle4 = 180° \)

Define Same Side Interior Angles.

• Pairs of angles that lie on opposite sides of the transversal and outside the two lines.

• Pairs of angles that lie on the same side of the transversal and between the two lines.

• Pairs of angles that are equal in measure and lie on the same line.

• Pairs of angles that are supplementary and lie on opposite sides of the transversal.

What is the sum of Same Side Interior Angles?

• 90°

• 180°

• 360°

• 120°

What are Alternate Interior Angles?

• Pairs of angles that lie outside two lines and on the same side of a transversal.

• Pairs of angles that lie between two lines and on opposite sides of a transversal.

• Pairs of angles that are equal in measure and lie on the same side of a transversal.

• Pairs of angles that are supplementary and lie between two lines.
