Geometry and Measurement

Geometry in Action

Geometry asks questions about shapes, angles, and measurements. On the ACT, you’ll encounter questions about lines, triangles, circles, and area and volume.

Key Concepts

  • Properties of Shapes: Know your triangles, quadrilaterals, and circles.
  • Perimeter, Area, and Volume: Use formulas to find measurements.
  • Angles: Understand complementary, supplementary, and vertical angles.
  • The Pythagorean Theorem: For right triangles, \(a^2 + b^2 = c^2\).

Everyday Applications

From designing a garden to building furniture, geometry helps you measure and create with precision.

Quick Tricks

  • Draw a diagram to visualize the problem.
  • Label all known values before starting calculations.

Examples

  • Finding the area of a triangle given its base and height.

  • Using the Pythagorean theorem to find the length of a ladder leaning against a wall.

In a Nutshell

Geometry helps you measure and understand the world’s shapes and spaces.
