Determine whether the triangles are similar. If so, write a similarity statement and name the postulate or the theorem you used. If not, explain.

The first pair of triangles are similar.

Triangle ABC is similar to Triangle PQR.

I used the SSS theorem of congruency.

( side - side - side) since I knew the sides were equal I knew that they were congruent.

----------------------------------------------------------

The second pair of triangles are similar too.

Triangle ABC is similar to Triangle DEF.

I also used the SSS theorem of congruency.

Since I knew what the sides were, I did some calculations and they all equalled 6...

I hope that helps you out!! Any more questions??
