1) What portion of the conditional statement is underlined in blue? Which portion is underlined in red?
If I drink water, then I stay hydrated.

2. Properties of Segment Congruence
Geometry
2.5 Day 2
I will justify statements about congruent segments.
Theorem 2.1
Properties of Segment Congruence
Reflexive
AB ≅ AB
Symmetric
IF AB ≅ CD, then CD ≅ AB
Transitive
IF AB ≅ CD, and CD ≅ EF, then AB ≅ EF

3. Definition of Congruent Segments
Given:
LK = 5 J K L
Ex 1
Given:
JK = 5
Given:
JK ≅ JL
Prove: LK ≅ JL
Step
Reason
LK = 5
Given
JK = 5
Given
Transitive Property
of equality
LK = JK
Definition of Congruent Segments
LK ≅ JK
JK ≅ JL
Given
Transitive Property
of equality
LK ≅ JL

4. Ex 2 Given: LE = MR Given: EG = RA Prove: LG = MA E L G R A M Step
Reason
LE = MR and EG = RA
Given
LE + EG = LG P2
MR + RA = MA P2

5. Ex 2 Given: LE = MR Given: EG = RA Like # 12 on quiz Prove: LG = MA E
Step
Reason
LE = MR and EG = RA
Given
LE + EG = LG P2
MR + RA = MA P2
Substitution Property of Equality
LE + EG = MA
Substitution Property of Equality
LG = MA
