Grade 12 Trig Identities & Equations Quiz
A free Grade 12 Trig Identities & Equations quiz. Play without signing up; sign in to save your score.
Grade 12 trigonometric identities are equations true for all allowed angles. Students use Pythagorean, reciprocal, and double-angle identities to simplify expressions and to solve equations. A proof of an identity rewrites one side into the other without assuming what was to be shown.

What you practice
These are the Grade 12 Trig Identities & Equations skills this quiz is built around.
- Apply sin²θ + cos²θ = 1 and the related tan and sec forms.
- Simplify an expression with a double-angle or sum identity.
- Solve a trigonometric equation on [0, 2π) after rewriting with an identity.
A useful tip
When you see 1 − sin²θ, replace it with cos²θ. Forcing a calculator decimal too early hides the identity that makes the algebra short.
