Similar shapes at a glance


Similar shapes are shapes which are the same shape but may be different sizes and/or may have been flipped or rotated. The corresponding angles between the shapes are the same. 


If two shapes are mathematically similar we can work out the scale factor of enlargement between the two shapes. For example, given two similar triangles, triangle ABC and triangle DEF, if we know that one side in triangle ABC is 4cm and the corresponding side in triangle DEF is 12cm then the scale factor is 124=3. We can then use this scale factor to work out missing lengths for the triangles. 


As well as 2d shapes such as quadrilaterals and polygons, 3d shapes can be similar. We can find the scale factor between two 3d shapes in the same way as 2d shapes. Area scale factors are equal to the scale factor squared and volume scale factors are equal to the scale factor cubed. 


Similarity is different to congruence in that for two shapes to be congruent they must be exactly the same shape and size whereas for two shapes to be similar they do not need to be the same size.


Looking forward, students can then progress to additional geometry worksheets, for example a 3D shapes worksheet or an area of compound shapes worksheet.
