Proof: Vertical Angles B

Let's prove the following theorem:

Proof:

Proof Table

#	Claim	Reason
1	m∠WPZ = m∠XPY	if m∠XPW = 180 and m∠YPZ = 180, then m∠WPZ = m∠XPY (Vertical Angles)
2	m∠XPY = m∠WPZ	if m∠WPZ = m∠XPY, then m∠XPY = m∠WPZ (Symmetric Property of Equality)
3	m∠XPY = m∠YPX	m∠XPY = m∠YPX (Angle Symmetry Property)
4	m∠YPX = m∠WPZ	if m∠XPY = m∠YPX and m∠XPY = m∠WPZ, then m∠YPX = m∠WPZ (Transitive Property of Equality Variation 2)
