To prove triangles similar by AA~, SSS~, or SAS~
3
4
But we now know that if corresponding angles are congruent and lengths of corresponding side are in proportion then two triangles are similar.
Is there a rule for proving triangles similar with less than all six pieces of information?
5
Angle Angle Similarity (AA~)
Side Side Side Similarity (SSS~)
Side Angle Side Similarity (SAS~)
6
If two corresponding angles are congruent, then the triangles are similar.
7
Open Ended
Write a similarity statement for the triangles.
8
If all corresponding sides are proportional, then the triangles are similar.
Some text here about the topic of discussion
9
Multiple Choice
Write the extended ratio to prove the triangles are similar.
63=85=410
1:2
36=48=510
The triangles are not similar.
10
If two corresponding sides are proportional and the included angles are congruent, then the triangles are similar.
11
Open Ended
