HiSet: High School Equivalency Test: Math

The HiSet Math subject prepares students for the mathematics section of the High School Equivalency Test, covering essential math skills and concepts.

Basic Concepts

Geometry & Measurement

Shapes and Spaces

Geometry is all about shapes, sizes, and how things fit together. You'll learn about lines, angles, circles, triangles, and more.

Measuring the World

Measurement means finding length, area, perimeter, and volume. You'll use units like inches, feet, meters, and liters. Knowing how to measure helps with tasks like building, cooking, and organizing spaces.

Why It Matters

Geometry shows up in art, design, maps, sports fields, and architecture. Measurement skills help you follow recipes, buy the right amount of paint, or figure out if a new sofa will fit in your room!

Handy Formulas

  • Perimeter of a rectangle: \( P = 2l + 2w \)
  • Area of a triangle: \( A = \frac{1}{2}bh \)

Examples

  • Measuring your room to see if a new bed will fit.

  • Calculating the area of a garden to buy enough soil.

In a Nutshell

Geometry and measurement let you understand and shape the space around you.

Key Terms

Perimeter
The distance around a shape.
Area
The amount of space inside a shape.
