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.
