### Sec 6-3 to 6-5

Concept: Use Similar Polygons

Objective: given 2 polygons, determine if they are similar and solve problems as measured by a s.g.

Example 1: Are the figures Similar?

If RSTUWXYZ List all pairs of corresponding congruent angles and write the ratios of the corresponding side.

Example 2

So, What is a scale Factor?_______________

3 Short Cuts

1. AATwo triangles are similar if two angles of one triangles are congruent to two angles of another triangle,

2. SSS Two triangles are similar if the corresponding side lengths of two triangles are proportional

3. SAS Two triangles are similar of an angles of one triangle is congruent to an angle of another triangle and the lengths of the sides including these angles are proportional.
