Advanced Topics

Geometry: Angles and Shapes

Exploring Lines, Angles, and Shapes

Geometry is all about shapes and their properties. You’ll learn to identify right, acute, and obtuse angles, and classify shapes like rectangles, squares, and parallelograms.

Measuring Angles

Use a protractor to measure angles in degrees. Remember, a right angle is 90 degrees!

Classifying Shapes

Shapes can be sorted by their sides, angles, and other features. Understanding how shapes are similar or different helps you solve many math puzzles.

Geometry in Real Life

Recognizing shapes and angles helps in art, building, and even sports!

Examples

  • Identifying a triangle as having three sides and three angles.

  • Spotting right angles in the corners of a picture frame.

In a Nutshell

Geometry helps you understand shapes, angles, and how they fit together.
