Questions focus on applying the Pythagorean theorem, identifying special right triangles (45-45-90 and 30-60-90), and using basic trig ratios (sine, cosine, tangent) to find missing sides or angles. Many problems combine these ideas in real-world contexts or coordinate planes, so strong recall of the core ratios leads to higher scores.
