Geometry

:

Congruence

Identify similar triangles.

###### 1:

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

###### 2:

Explain that triangles are similar if all corresponding angles are equal and all corresponding sides have the same ratio or proportion.

###### 3:

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

6th

###### Vocabulary:

SIMILAR TRIANGLES, ANGLE-ANGLE SIMILARITY, SIDE-SIDE-SIDE, SIDE-ANGLE-SIDE, CORRESPONDING SIDES, CORRESPONDING ANGLES

Activities:

- Sorted sets of triangles for which the three side lengths were given into two categories: Similar, Not similar

- Confirmed the results by writing ratios of corresponding side lengths and using the Side-Side-Side Theorem

- Explored Side-Angle-Side Theorem by creating similar triangles given two sides and the angle in between.    ### Home Exploration
