Proof: Angle Symmetry Example 2

Let's prove the following theorem:

if m∠ABC = x, then m∠CBA = x

Proof:

View as a tree | View dependent proofs | Try proving it

Given

1	m∠ABC = x

Proof Table

#	Claim	Reason
1	m∠ABC = m∠CBA	m∠ABC = m∠CBA (Angle Symmetry Property)
2	m∠CBA = x	if m∠ABC = m∠CBA and m∠ABC = x, then m∠CBA = x (Transitive Property of Equality Variation 2)
