Geometric Properties

Question 1

Definition of Congruence

Answer 1

If mAB = mBC then AB= BC & if AB= BC then mAB = mBC

(m = measure of)

Question 2

Angle Addition Postulate

Answer 2

If S is in the interior of <QPR then m<PQR +m<SQR= m<PQR

Question 3

Definition of Midpoint

Answer 3

A point that divides a segment into 2 equal parts & is the halfway point on the given line segment.

Question 4

Segment Addition Postulate

Answer 4

If B is between A & C, then measure the line of segment AB plus measure the line of segment BC equals the measure of line segment AC

Question 5

Transitive Property of Congruence

Answer 5

If A is congruent B and a C. then AC

(if A & B are the same | then B & C are the same , A & C have to be the same)

Question 6

Reflexive Property of Congruence

Answer 6

Shows that something congruent to itself <ABC is congruent <ABC

(think of looking at yourself in a mirror )
