Question 16

Reflexive Property of Congruence

Answer 16

For any segment AB, AB ≅ AB (there is a line above the segment but I can’t type it on the flashcard)

Question 17

Symmetric Property of Congruence

Answer 17

If AB ≅ CD and CD ≅ EF, then AB ≅ EF (there is a line above the segment but I can’t type it on the flashcard)

Question 18

Transitive Property of Congruence

Answer 18

If AB ≅ CD and CD ≅ EF, then AB ≅ EF (there is a line above the segment but I can’t type it on the flashcard)

Question 19

Definition of Congruence (Congruence)

Answer 19

Segments are congruence if and only if they have the same measure

Question 20

Definition of Midpoint

Answer 20

The midpoint of a segment divides the segment into 2 equal/congruent parts.

Ex. If M is the midpoint of AB, then AM = MB.

Question 21

Segment Addition Postulate

Answer 21

If A, B and C are collinear points and B is between A and C.

Ex. AB + BC = AC

Question 22

Definition of Congruence (Angle)

Answer 22

m<A = m<B <–> <A ≅ <B

Question 23

Definition of Angle Bisector

Answer 23

An angle bisector divides an angle into two equal parts (= or ≅)

Question 24

Definition of Complementary Angles

Answer 24

Complementary <–> Sum is 90º

Question 25

Definition of Supplementary Angles

Answer 25

Supplementary <--> Sum is 180º

Question 26

Definition of Perpendicular

Answer 26

Perpendicular lines form right angles
