Key Features

A triangle with three different sides and three different angles.

Lines of Symmetry?

None.

Rotational Symmetry?

None.

right angled triangle
Right-Angled Triangle

Key Features

A triangle with one right-angle.

Can a Triangle be Right-Angled and Isosceles?

Yes.

Lines of Symmetry?

Only if it’s an isosceles triangle - one line.

Rotational Symmetry?

None.

quadrilateral
Quadrilateral

Key Features

A shape with four sides.

Lines of Symmetry?

It depends on what sort of quadrilateral it is.

Rotational Symmetry?

It depends on what sort of quadrilateral it is.

Names of Special Quadrilaterals

Rectangle, Square, Parallelogram, Trapezium, Rhombus, Kite.

rectangle
Rectangle

Key Features

A quadrilateral with four right-angles.Opposite sides are the same length.

Lines of Symmetry?

Two, unless the rectangle is a square.

Rotational Symmetry?

Order 2, unless the rectangle is a square.

Is a Rectangle a Parallelogram?

Yes, because both pairs of opposite sides are parallel.

square
Square

Key Features

A quadrilateral with four equal sides and four right-angles.

Lines of Symmetry?

Four.

Rotational Symmetry?

Order 4.

Is a Square a Rectangle?

Yes, because it’s a quadrilateral with four right-angles.

Is a Square a Parallelogram?

Yes, because both pairs of opposite sides are parallel.

Is a Square a Rhombus?

Yes, because it’s got four sides all the same length.

parallelogram
Parallelogram

Key Features

A quadrilateral with opposite sides that are parallel and the same length.

Lines of Symmetry?

Only if it’s a rectangle, a square or a rhombus.

Rotational Symmetry?

Order 2.

oblong
Oblong

Key Features

A rectangle which is not a square.

Lines of Symmetry?

Two.

Rotational Symmetry?

Order 2.

Is an Oblong a Parallelogram?

Yes, because both pairs of opposite sides are parallel.

trapezium
Trapezium

Key Features

A quadrilateral with just one pair of parallel sides.

Lines of Symmetry?

Only if it’s an isosceles trapezium.

Rotational Symmetry?

None.

rhombus
Rhombus

Key Features

A quadrilateral with four equal sides.

Lines of Symmetry?

Two.

Rotational Symmetry?

Order 2.

Is a Rhombus a Parallelogram?

Yes, because both pairs of opposite sides are parallel.
