Geometry Weekly Plan
Feb. 29 to Mar. 4, 2016
Common Core Standards:
G-SRT-5: Use congruence and similarity criteria for triangles to solve problems and to prove relationships
in geometric figures.
G-SRT-6: Understand that by similarity, side ratios in right triangles are properties of the angles in the
triangle, leading to definitions of trigonometric ratios for acute angles.
G-SRT-7: Explain and use the relationship between the sine and cosine of complementary angles.
G-SRT-8: Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied
problems.
