5 mar 2024 · Two shapes are mathematically similar if one is an enlargement of the other. If two similar shapes are linked by the scale factor, k. Equivalent areas are linked by an area factor, k2. Equivalent volumes are linked by a volume factor, k3.
Calculate the size of a missing length, area or volume on a similar figure using the enlargement/reduction scale factor as part of National 5 Maths.
Calculate the size of a missing length, area or volume on a similar figure using the enlargement/reduction scale factor as part of National 5 Maths.
Similar Figures are used to examine the relationship of length, area and volume between two shapes. Consider the two similar shapes (cubes) below: . In the above, linear scale factor = 8/4 = 2. To find an unknown length, area or volume in similar shapes: Length: Use (linear scale factor) as the multiplier.
Scaling Similar Shapes. When you scale a shape, you multiply every single distance by the same scale factor to create a new version of the shape that is similar to the original version, but bigger or smaller. It's important to note that every single distance is multiplied by the same factor, whether explicitly marked on a drawing or not.
