Proof: Isosceles Triangle 2

Let's prove the following theorem:

Proof:

Proof Table

#	Claim	Reason
1	distance XZ = distance YZ	if distance ZX = distance ZY, then distance XZ = distance YZ (Distance Property 3)
2	m∠YXZ = m∠XYZ	if distance XZ = distance YZ, then m∠YXZ = m∠XYZ (Angles of an Isosceles Triangle)
3	m∠ZXY = m∠ZYX	if m∠YXZ = m∠XYZ, then m∠ZXY = m∠ZYX (Angle Symmetry 2)
