Skills in this topic

Match opposite, adjacent, and hypotenuse.
Use sine, cosine, and tangent ratios.
Work with special angles and right-triangle problems.

Worked example

In a right triangle, the opposite side is 3 and the hypotenuse is 5. sin θ = 3/5 = 0.6. The angle is approximately 36.87°.

How the Ladder Works

Six levels run from Warm-Up to Mastery. Warm-Up has five questions; later sets grow to eight or nine depending on the topic. Clear a level with at least 80% first-try accuracy. Every level is available from the start, and retries produce fresh questions.

Hints and worked solutions support practice. Grades 9–11 is a guide, not a restriction.
