As part of your work in KS3 Maths, you'll have come across a variety of shapes. Circles, triangles, pentagons and more. This particular quiz is all about quadrilaterals.
Quadrilaterals are two dimensional shapes that have four sides and four angles. Squares and oblongs spring to mind but there are different kinds of quadrilaterals, each with different properties. As their name suggests, quadrilaterals have four sides (this comes from Latin, with QUAD meaning 4, and LATERAL meaning sides). What other properties do they have? Well, the interior angles of a quadrilateral always add up to 360^{o}.
There are some other rules, such as lengths of sides or whether they are parallel which classify quadrilaterals into different types  rhomboids or trapeziums for example. Try the quiz that follows and see how well you know your quadrilaterals.














A circle does not have four sides

All four sides MUST be equal too


The definition of a trapezium is a quadrilateral with at least one pair of parallel sides

A kite is a quadrilateral whose four sides can be grouped into two pairs. Each pair is adjacent and of equallength


A triangle does not have four sides

By adding a diagonal you can split a quadrilateral into 2 triangles. The sum of the angles in a triangle is 180^{o}, so the sum of two triangles will be 360^{o}


Just as a scalene triangle has sides of unequal length, the same is true of a scalene quadrilateral

If it did have a line of symmetry then it would be either a rhombus or a rectangle


Just as an isosceles triangle has two sides of equal length, so too with an isosceles trapezium which makes it symmetrical

A rhombus is like a 'squashed' square or a diamond
