Discovering Trigonometric Ratios WORKSHEET
Suitable for Grades: Geometry, Algebra II
CCSS: HSG.SRT.C.6
CCSS Description: 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
Discovering Trigonometric Ratios WORKSHEET DESCRIPTION
This worksheet is designed to provide an opportunity for learners to discover the relationships between the side lengths of right angle triangles and the trigonometric ratios sin, cos, and tan. The first three sections provide sets of similar triangles for learners to measure the specified lengths and angles, and then compare the ratios of the chosen sides with the relevant trig function. The remaining sections are helpful to consolidate which side lengths match to which trig function.
