# How many sides and angles are on a square, circle, triangle, and rectangle?

Posted on

A square and a rectangle each have 4 sides and 4 angles. The only difference between them is that a square is a rectangle with equal sides. Both have 4 90 degree (right) angles.

A triangle has 3 sides and 3 angles. The angles of a triangle always add up to 180 degrees.

The closest thing a circle has to a side is the circumference (the circle itself).  It also has an area (the space inside the circle) and a radius and diameter. The diameter is the distance from one side of the circle to the other, passing through the midpoint. The radius is half that distance – from the midpoint to the circumference. The “angle” of a circle is 360 degrees – all the way around.

square, circle, triangle, and rectangle

a square has 4 sides that are all equal, and 4 90 degrees angles

a circle, round no angles or sides 360 degrees

triangle - has 3 sides and 3 angles (The name triangle) 180 degrees all together

Rectangle  - 4 sides, each pair equal add up to 360 degrees

Square- 4 sides   each side is 90 degree and total angle is 360 degree

Circle- has no side    360 degree angle

Triangle- 3 sides; each side is 60 degree and total angle is 180 degree

Rectangle:4 sides

each side is 90 degree and total angle is 360 degree

SQUARE:

• Sides: 4 sides
• Angles: 4 right angles (Right angles are 90 degrees). Add up to 360 degrees

CIRCLE:

• Sides: None; since it is round
• Angles: Angles add up to 360 degrees

TRIANGLE

• Sides: 3 sides
• Angles: Add up to 180 degrees

RECTANGLE:

• Sides: 4 sides
• Angles: 4 right angles (Right angles are 90 degrees). Add up to 360 degrees
