Shapes

🔹 What Are Shapes?

Shapes are figures made by lines, curves, or both.
They can be flat (2D) or solid (3D).

Examples of 2D Shapes:

• Triangle
  
  

• Square
  
  

• Rectangle
  
  

• Circle
  
  

• Pentagon
  
  

Each shape has sides and corners (called vertices).
A square has 4 equal sides and 4 right angles.
A triangle has 3 sides and 3 angles.

💡 Why It Matters

Shapes are all around us — in buildings, designs, patterns, and tools.
Understanding them helps with drawing, building, measuring, and even problem solving.
