Unit3 Review

Figure 4 should have parallel lines. You can predict this because:

• The 2 angles are vertical and they would be congruent

• The 2 angles are corresponding and they would be congruent

• RQ would be equal to RV so R is the midpoint

• The 2 angles are same side exterior and they would be congruent

What conjecture can be made about the relationship shown in the pattern between parallel and angles?

• If 2 parallel lines are cut by a traversal, then same side interior angles are congruent

• if 2 parallel lines are cut by a traversal then alternate exterior angles are congruent

• Vertical angles are congruent if and only if lines are parallel

• Adjacent angles are congruent if and only if lines are parallel

If this pattern continues, which of the following statements about Figure 4 must be true?

• All of these

• AB || CD

• FE PERPENDICULAR TO AB

• m<EFC = 90 DEGREES

If you were to connect points b and c what would be created?

• Adjacent angles

• Parallel lines

• Obtuse angle bisector

• Perpendicular bisector of a line segment

Which of these is NOT true?

• QR = PN

• m<RQP = m<QPM

• <LQP is complementary to <QPM

• <QPM and <NPQ form a linear pair

AB || CD m<LRB = (3x – 2)°, and m<RSC = (2x – 5)°

Find m<CSK in degrees.

• m<CSK = 37.4°

• m<CSK = 69.8°

• m<CSK = 110.2°

• m<CSK = 56.2°

If m < G = 72° what is the m < D?

• 94°

• 108°

• 18°

• 72°

m< E = m < H because they are:

• Corresponding angles

• Same Side interior

• Alternate exterior

• Vertical angles

m < B and m< F are:

• Corresponding angles

• Vertical Angles

• Same side interior

• Same side exterior
