Lesson details
Key learning points
- Two similar shapes can be described as being 'x' times greater or smaller than each other.
- If one similar shape is smaller than another, the scale factor is a fraction.
- Shapes related by a scale factor are similar.
Keywords
Dimensions - The dimensions of an object or shape are the lengths of its sides and edges
Scale factor - A scale factor is the ratio between the dimensions of the original shape and the new shape. The scale factor can be an integer or a fraction
Regular polygon - A regular polygon has all sides the same length and all angles equal
Similar shapes - Similar shapes can be transformed into each other by scaling their dimensions by the same scale factor
Common misconception
That regular polygons include all familiar shapes even if they don't meet the definition.
Reinforce the definition and apply to the regular shapes which appear in this lesson.
