Similar Shapes (Area and Volume) Teaching Resources
G19a Lengths, areas and volumes in similar shapes
What are similar shapes? Similar shapes are enlargements of each other using a scale factor. All the corresponding angles in the similar shapes are equal and the corresponding lengths are in the same ratio. E.g. These two rectangles are similar shapes. The scale factor of enlargement from shape A to shape B is 2 2. The angles are all 90^o 90o

Similar Shapes GCSE Maths Steps, Examples & Worksheet
The ratio of the area of two similar triangles is equal to the square of the ratio of any pair of the corresponding sides of the similar triangles. If two triangles are similar it means that: All corresponding angle pairs are equal and all corresponding sides are proportional.

Start Lesson Back In this lesson, we will identify similar shapes and subsequently work out areas of similar shapes using our knowledge of scale factors.
Area of Similar Figures IGCSE at Mathematics Realm
Similar figures are identical in shape, but not necessarily in size. A missing length, area or volume on a reduction/enlargement figure can be calculated by first finding the scale factor..
Similar Shapes GCSE Maths Steps, Examples & Worksheet
Solution: Linear scale factor = 4 Area scale factor = 42 ( = 16 ) New surface area: 3.5 ร 16 = 56 m2 Volume scale factor: If we take a cuboid of length 3 cm and breadth 2 cm 4 cm and height 4 cm then the 3 cm 2 cm Volume = 3 ร 2 ร 4 = 24 cm3.

Area and Volume of Similar Shapes (A) Worksheet Cazoom Maths Worksheets
To find the area of two similar shapes we can use the knowledge that the ratio of their areas is equal to the ratio of the square of their respective sides. Let us take an example; ABC \ (\sim\) DEF So their corresponding parts must be proportional \ (\frac {AB} {DE}=\frac {AC} {DF}=\frac {BC} {EF}\)

G19a Lengths, areas and volumes in similar shapes
The Relation between the Area of Similar Figures. When two figures are similar, the square of the ratio of their corresponding side lengths equals the ratio of their area. When the ratio of two corresponding sides (or other lengths) is expressed as \ (\frac {a} {b}\), in similar figures, the ratio of the areas is expressed as \ (\frac {a^2} {b^2}\)
