Trigonometric Ratios: Missing Side Lengths and Angle Measures 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

Trigonometric Ratios: Missing Side Lengths and Angle Measures WORKSHEET DESCRIPTION

This worksheet provides some purposeful practice for finding the missing angles and lengths of right angle triangles using trigonometry (SOHCAHTOA). The questions in Section A involve finding the missing angle, section B involves both angles and lengths, and section C provides three problem solving questions involving compound shapes and a trapezoids.

All worksheets are created by the team of experienced teachers at Cazoom Math.

Frequently Asked Questions

This worksheet is designed for students in Algebra II and Geometry courses. These grade levels typically cover trigonometric ratios and right triangle relationships, making it perfect for reinforcing SOHCAHTOA concepts. Students at this level should have the foundational knowledge needed to work with sine, cosine, and tangent ratios.
