What Are 2D Shapes?

2D shapes are flat figures you can draw on paper, with only length and width. Think of a pizza, a notebook, or a traffic sign—these are all 2D shapes! In geometry, 2D shapes have unique features like sides, angles, or curves, making them a key part of math for CBSE, ICSE, and state board students.

Most 2D shapes, like triangles and squares, are polygons with straight sides. Others, like circles, have curved edges. Understanding 2D shapes is essential for geometry lessons and exams, and Studit’s expert tutors in Bhubaneswar are here to make it easy!

Types of 2D Shapes

Here are the most common 2D shapes you’ll study in school:

Circle

A circle is a round 2D shape where every point on the edge is equidistant from the center (radius). Examples include:

• A round pizza
• A coin
• A clock face

Triangle

A triangle is a three-sided polygon with three angles that add up to 180°. Look for triangles in:

• A slice of pizza
• A yield traffic sign
• A kite

Square

A square is a four-sided polygon with equal sides and 90° angles. It’s a regular polygon. Examples include:

• A chessboard
• A square tile
• A photo frame

Rectangle

A rectangle has four sides with opposite sides equal and parallel, all at 90° angles. Examples include:

• A smartphone screen
• A book
• A window

Pentagon

A pentagon is a five-sided polygon. In a regular pentagon, all sides and angles (108° each) are equal. Examples include:

• A starfish
• A pentagonal garden patch
• A home plate in baseball

Octagon

An octagon has eight sides and eight angles, with interior angles totaling 1080° in a regular octagon. Examples include:

• A stop sign
• An octagonal mirror
• A decorative plate

Area and Perimeter of 2D Shapes

The area is the space inside a 2D shape, and the perimeter is the distance around its edges. Here are the formulas for common 2D shapes:

These formulas are essential for CBSE, ICSE, and state board exams. Practice with Studit’s expert tutors to ace your geometry questions!

Solved Examples

Try these practice questions to test your skills:

Q1: What is the area of a square with a side length of 7 cm?

Solution:
Area of a square = side²
= 7 × 7 = 49 cm²
Answer: 49 cm²

Q2: Find the perimeter of a rectangle with a length of 12 cm and a breadth of 5 cm.

Solution:
Perimeter of a rectangle = 2(length + breadth)
= 2(12 + 5) = 2 × 17 = 34 cm
Answer: 34 cm

Q3: What is the area of a circle with a radius of 3 cm? (Use π = 3.14)

Solution:
Area of a circle = πr²
= 3.14 × 3² = 3.14 × 9 = 28.26 cm²
Answer: 28.26 cm²
