STANDARD G.SRT.B.5
GEO
Use congruence and similarity criteria for triangles to:
a. Solve problems algebraically and geometrically.
b. Prove relationships in geometric figures.
• ASA, SAS, SSS, AAS, and Hypotenuse-Leg (HL) theorems are valid
criteria for triangle congruence. AA~, SAS~, and SSS~ are valid
criteria for triangle similarity.
• This standard is a fluency recommendation for Geometry.
Fluency with the triangle congruence and similarity criteria will
help students throughout their investigations of triangles,
quadrilaterals, circles, parallelism, and trigonometric ratios.
These criteria are necessary tools in many geometric modeling tasks. |
