:

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.

Vocabulary:

SIMILAR TRIANGLES, SIDE-SIDE-SIDE THEOREM, ANGLE-ANGLE THEOREM, SIDE-ANGLE-SIDE THEOREM, CORRESPONDING SIDES AND ANGLES

Activities:

- Sorting Activity (Part 1) - Classified given similar triangles according to the similarity theorem shown (SSS, AA, SAS)

- Used proportions to solve for missing side lengths in similar triangles.
