We want to identify what pair of triangles are similar on the figure shown.

For doing so, we will use what we are given: GRPC is a parallelogram, and the measures on the graph, to find some values.

We have that:

[tex]GR=CP=CB+BP=325ft+225ft=550ft[/tex]

Also,

[tex]GC=RP=375ft[/tex]

Part A and B

For this part, we will identify similar triangles. We say that:

[tex]\begin{gathered} \Delta GCB\sim\Delta BEP \\ \Delta GCB\sim\Delta GRE \end{gathered}[/tex]

First, we will show that the triangles GCB and BEP are similar. This happens because the angles

[tex]\angle EBP\cong\angle CBG\text{ as they are opposite by the vertex}[/tex]

And:

[tex]\angle BGC\cong\angle BEP[/tex]

as the lines GC and RP are parallel (because GRPC is a parallelogram) and the line BG is a transversal to parallel lines. Thus, by the criteria AA, the triangles are similar.

Now, we will show that the triangles GCB and GRE are similar.
