Keep reviewing just acquired concepts : sequences, similar triangles, dimensional changes.
Concept-based homework will be sent out through e-mail.

For this week's work. learn to get all the sides fast for the two special right triangles and
be able to get the area of any polygon using the shoestring method.

From Art of Problem Solving of some triangles:
Isosceles and Equilateral Triangles
Isosceles Right Triangles (45-45-90 degree special right triangles)
30-60-90 Degree Special Right Triangles
From my blog
Pythagorean triples for Mathcounts/AMCs
Triangles share the same vertices.
