CCSS.HSF.BF.A.2

Make a conjecture about the value or geometric relationship. (State something that is true.)

Point P is the midpoint of segment NQ.

• NQ + NP = PQ

• NP = PQ

• NQ = NP

• QP + NQ = NP

CCSS.HSG.CO.A.1

Make a conjecture about the value or geometric relationship. (State something that is true.)

angle 1 and angle 4 form a linear pair

• angle 1 and angle 4 are complementary

• angle 1 is congruent to angle 4

• angle 1 + angle 4 = 90

• angle 1 and angle 4 are supplementary

CCSS.7.G.B.5

Determine whether the conjecture is true or false.

If angle 1 and angle 2 are adjacent angles, then angle 1 and angle 2 form a linear pair.
