Additional Topics in Math
The PSAT 10 Math Test also contains two questions in Additional Topics in Math (one in the no-calculator portion and one in the calculator portion). The questions may include topics like geometry, trigonometry, radian measure, and complex numbers.
Questions of this type may include the following:
-
Solve problems using volume formulas.
-
Use trigonometric ratios and the Pythagorean theorem to solve applied problems involving right triangles.
-
Add, subtract, multiply, divide, and simplify complex numbers.
-
Convert between degrees. Use radians to determine arc lengths. Use trigonometric functions of radian measure.
-
Apply theorems about circles to find arc lengths, angle measures, chord lengths, and areas of sectors.
-
Use concepts and theorems about congruence and similarity to solve problems about lines, angles, and triangles.
-
Use the relationship between similarity, right triangles, and trigonometric ratios. Use the relationship between sine and cosine of complementary angles.
-
Create or use an equation in 2 variables to solve a problem about a circle in the coordinate plane.
