### Target 1

###### Lesson Type:

Continuation

Geometry

:

Congruence

Identify similar triangles.

###### Supporting targets:

###### 1:

Prove that triangles are similar using SSS (Side-Side-Side), AA (Angle-Angle), and SAS (Side-Angle-Side).

###### 2:

Use the corresponding sides of similar triangles to determine the unknown length of a side.

###### 3:

Find the ratio of corresponding sides and use that ratio to find unknown lengths.
