Right Triangles: Finding Trig Ratios - Secant, Cosecant, and Cotangent
✓ There are two sets of 32 Task Cards, one with QR codes
and one without. Students find trigonometric ratios from a given right triangle. The triangles pictured are not drawn to scale. They also are not all ABC triangles. Various letters are used for the vertices. This way students do not memorize b over c, or a over b. They must look carefully at each triangle and apply the rules.
Students do not need the internet to use the QR’s, but they do need to have a device with a QR reader app installed.
✓ Answer key
✓ Student response sheet
✓ Extra handout
which can be used as an assessment, HW, enrichment, or for an absent student.
