The name given to flat shapes that occupy a space and thus have area that
can be calculated.
Two-Dimensional (2-D)
A polygon whose sides are all the same length, and whose angles are all the
same size.
Regular Polygon
A polygon that does not have sides that are the same length, nor are the
angles the same size
Irregular Polygon
A shape that is equilateral has all its sides the same length.
Equilateral
The distance around a polygon.
Perimeter
An expression or equation that is used to express the relationship between
certain quantities.
Formula
The surface of a shape or object. It can also be defined as the number of
square units that a shape covers.
Area
An irregular shape that is made up of parts or whole components of other
shapes.
Composite Shape
How does one find the perimeter of a square?
The length of all 4 sides are added together
What is the perimeter of a square with sides that are 2.5cm?
2.5 + 2.5 + 2.5 + 2.5
= 10cm
How does one find the area of a square or a rectangle?
By multiplying the length by the breadth
Work out the area of a room where the
Length is 2.5m and the breadth is 1.2m
Calculate
How does one work out the perimeter of a triangle?
The length of all 3 sides are added together
How does one calculate the area of a triangle?
the base is multiplied by the perpendicular height then
multiplied by half
Work out the area of some triangles.
Calculate
When dealing with more unusual shapes, how would one work out the area?
they need to broken up into one or more of
the more familiar shapes in order to find the area or the perimeter of them

What is a cube?
A 3D figure with 6 identical square faces
A solid object with 2 identical ends and flat sides. The cross section is the same
all along the length
A Prism / Polyhedron
A prism made of 6 rectangular faces
A rectangular Prism
A special type of polyhedron. It has a polygon base and the other faces are
triangles that meet at an apex
Pyramid
These are figures that do not lie in a plane. The figures have length, breadth and
height or depth.
3 Dimensional (3-D)
The flat surface or side of a solid shape
Face
the intersections of the faces of a solid figure
Edge
The corner of a solid shape. The point where the edges meet
Vertex
The highest point or peak of a pyramid.
Apex
The sum of the areas of each of the faces of a 3D shape
Surface Area
The amount of space contained inside a shape. That means volume is the space
that can be filled with other items
Volume
What is volume measured in
Cubic units
What is area measured in
Square Units
The amount of liquid that a 3D shape can hold. It is measured in ml or l
Capacity
A 2D pattern that folds to form a 3D shape. It is helpful when calculating
surface area as it makes all faces visible, so that they are not omitted from the
calculation.
