2D Shapes - Quadrilaterals
Quadrilaterals are 2 dimensional shapes which have four sides, four angles and four vertices. The four angles of a quadrilateral always add up to 360°.
_________________________________________________________
Square |
4 sides of equal length
4 vertices
4 equal angles
The angles of a quadrilateral always add up to 360°, therefore each angle of a square
is,
360 ÷ 4 = 90° |
|
Rectangle
|
2 pairs of equal sides
4 vertices
4 equal angles
The angles of a quadrilateral always add up to 360°, therefore each angle of a rectangle
is,
360 ÷ 4 = 90° |
|
Rhombus
|
4 equal sides
Opposite sides are parallel
Opposite angles are equal
(like a pushed over square)
|
|
Parallelogram
|
2 pairs of equal sides
Opposite sides are parallel
Opposite angles are equal
(like a pushed over rectangle)
|
|
Trapezium
|
1 pair of parallel sides of different lengths
|
|
Kite
|
2 pairs of equal sides next to each other
No parallel sides
1 pair of opposite equal angles |
|

Remember
All the angles of a quadrilateral add up to 360°
