Introduction

Geometry is a branch of mathematics that deals with shapes, sizes, and properties of objects in space.

Shapes and Their Properties

• Circle: A circle is a shape with all points the same distance from the center. For example, a clock face is a circle.
• Triangle: A triangle has three sides and three angles. Think of a slice of pizza - it's a triangle!
• Rectangle: A rectangle has four sides and four right angles. Your notebook is shaped like a rectangle!

Lines and Angles

• Parallel Lines: Parallel lines are lines that never meet, no matter how far they are extended. Train tracks are a good example of parallel lines.
• Right Angle: A right angle is 90 degrees. Imagine the corner of a book - that's a right angle!

Fun Activity

Draw different shapes on a piece of paper and label their properties. For example, draw a square and write that it has four equal sides and four right angles.

Remember

• Shapes have different properties.
• Lines can be parallel or intersecting.
• Angles can be acute, right, or obtuse.
