Geometry tuition – 2D maths shapes | Academic Owl Tuition – London Tutors

First you need to learn the name of maths shapes and then you have to calculate the perimeter  area or volume, depending on the level you are on. We are only going to remember the 2D shapes.

First of all, a 2D shapes is a shape that can be represented on a bi-dimensional graphic which has two axis: X and Y.

The most common geometric shapes are:

square

Aria= s*s

Perimeter= 4*s

rectangle

Aria = l * L

Perimeter= 2L+2I

All angles have 900

parallelogram

Aria = l * L

Perimeter= 2L+2I

L is parallel with L and the other two sides are parallel to each other

triangle

Perimeter = 3*a

rhombus

Perimeter= 4*l

Aria= d2*d1/2

trapezium

Aria= (l+L)*h/2

The trapezium has four sides, two of them are parallel, one is smaller than the other.

pentagon

Any pentagon has five sides

hexagon

All hexagons have six sides

octagon

This shape is called like this because it has eight sides

circle

Perimeter= 2∏r

Aria= ∏ r2

Geometry lessons are very interesting and catchy if you have a geometry tutor who knows how to teach you.
