CPM Homework Help : CCG Problem 8-30

Triangles, Q R P, & Q R S, overlap with sides, R P, & Q S, intersecting at point, T. In the figure at right, if $PQ = SR$ and $PR = SQ$ , prove that $\angle P \cong \angle S$ . Write your proof either in a flowchart or in two-column proof form.

Answer:

Statement	Reason
$PR=SQ$	Given
$PQ=RS$	Given
$QR=QR$	Reflexive
$ΔPQR≅ΔSRQ$	$\text{SSS}≅$
$∠P≅∠S$	$≅Δ\text{s}→≅\text{Parts}$

Be sure to look at the reasoning and understand why this proof is organized as it is.
