Sides

In geometry, a side is a straight line that forms part of the boundary of a two-dimensional shape or three-dimensional solid. The number of sides a shape has depends on its type. Here are a few examples:

• Triangle: A triangle has three sides.
• Square: A square has four sides.
• Pentagon: A pentagon has five sides.
• Hexagon: A hexagon has six sides.

To calculate the perimeter of a shape, you add up the lengths of all its sides. For example, if you have a square with side lengths of 4 units, you would calculate the perimeter by adding 4 + 4 + 4 + 4, which equals 16 units.

Study Guide

Here are some key points to remember about sides:

1. Identify the type of shape you are dealing with to determine the number of sides.
2. To calculate the perimeter, add up the lengths of all the sides.
3. Practice identifying and counting the sides of different shapes to reinforce your understanding.

Remember, the number of sides a shape has is an important characteristic that helps us classify and understand different geometric figures.
