Free SAT Right triangles and trigonometry Practice Questions
Right-triangle trigonometry on the SAT means sine, cosine and tangent as side ratios, plus the Pythagorean theorem and the two special triangles. Questions are short; the work is identifying which side is opposite and which is adjacent.

How the SAT tests right triangles and trigonometry
You find missing sides and angles using trigonometric ratios, apply the Pythagorean theorem, and use the 30-60-90 and 45-45-90 relationships.
Where the points go
Mixing up opposite and adjacent relative to the referenced angle, and using the hypotenuse as a leg.
Every question you miss here is added to your mistake log with the specific error identified, and brought back after three days and again after fourteen — no screenshots, no error journal to keep.
