Triangle Similarity Quest on Wenesday, 5/12
Unit 12 Quest Topics:
*Congruence proofs with overlapping triangles
* Isosceles Triangle Theorem and Converse
* Triangle Inequalities
* Similarity Shortcuts (AA, SAS, SSS) and proofs
* Solving and using proportions
* Special segments in triangles
* Proportional parts of triangles (Side Splitter Theorem)
* Right triangle similarity
* Solving for unknowns in similar triangles
Homework
Monday:
Side-Splitter WS
Copy the following onto your Justifications sheets:
Side-Splitter Theorem: If a line intersecting two sides of a triangle is parallel to the third side, then it divides the two sides proportionally.
Converse of the Side-Splitter Theorem: If a line intersecting two sides of a triangle divides those two sides proportionally, then the line is parallel to the third side.
If the altitude is drawn to the hypotenuse of a right triangle, then the two triangles are similar to the original triangle and to each other.

SSS Congruence Postulate: If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
SAS Congruence Postulate: If two sides and an included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
ASA Congruence Postulate: If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
AAS Congruence Theorem: If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
HL Congruence Theorem: If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent.
