Geometry Basics

Exploring Shapes and Space

Geometry deals with the properties and relationships of points, lines, surfaces, and solids. On the GMAT, you'll see questions about area, perimeter, volume, and angles.

Main Topics

  • Triangles, circles, quadrilaterals, polygons
  • Perimeter and area of 2D shapes
  • Volume and surface area of 3D figures
  • Angles and parallel lines

Geometry in the Real World

Geometry helps you understand how much paint you’ll need for a wall or how to pack a box efficiently.

Handy Hints

  • Memorize key formulas for area and volume.
  • Draw diagrams to visualize complex problems.

Watch Out

  • Don’t assume diagrams are to scale unless stated.
  • Remember that all triangle angles sum to 180°.

Drawing Conclusions

Geometry is not just about memorizing formulas—it's about visual thinking and logical deduction.

Examples

  • The area of a triangle with base 10 and height 5 is (1/2) × 10 × 5 = 25.

  • A rectangle with sides of 4 and 7 has a perimeter of 2 × (4 + 7) = 22.

In a Nutshell

Geometry is the study of shapes, sizes, and the properties of space.
