Step Reason
Section 6.2 Day 2
I will use properties of parallelograms.
ABCD and AEFG are Given
Ex 1 ABCD and AEFG are parallelograms.Given:
Prove: ∠1 ≅ ∠ 3
∠1 ≅ ∠ 2∠2 ≅ ∠ 3 ∠1 ≅ ∠ 3
Opposite ’s of a are .∠ ≅
Opposite ’s of a are .∠ ≅
Transitive Property of Equality
Prove: ∠A ≅ ∠C
Step Reason
Given
Reflexive Property of Congruence
ΔABD ≅ ΔCBD SSS
∠A ≅ ∠C CPCSC
∠B ≅ ∠D CPCSC
Ex 2
ABCD is a
A
D
B
C
∠B ≅ ∠D
Opposite sides of ≅
Opposite sides of ≅
AD ≅ BC
AB ≅ DC
BD ≅ BD
Ex 3
4m - 7 = m + 14
3m = 21
m = 7
4k - 2 = k + 28
3k = 30
m + 144k - 2
4m - 7
k + 28
k = 10
