Two shapes are Similar when one can become the other after a resize, flip, slide or turn. Resizing. If one shape can become another using Resizing (also called dilation, contraction, compression, enlargement or even expansion), then the shapes are Similar: These Shapes are Similar!
Forgetting that shapes can be similar but in different orientations The second shape may be in a different orientation to the first shape. The shapes can still be similar. For example, here shape A and Shape B are similar. Shape B is an enlargement of shape A by scale factor 2. Here, shape B has been rotated to make the similarity easier to see.

Producing similar figures. The dilation transformation produces similar figures that are not necessarily the same size. ABC is dilated by a factor of (its size is reduced by but its shape is the same) to produce DEF so that , , and . The ratios of the sides are: , , and , and the shape of the triangles is the same. Therefore, ∠A≅∠D, ∠B ...

Similar vs congruent shapes. Similar shapes have the same shape but not necessarily the same size. Two shapes that are exactly the same size and shape are called congruent shapes. See Congruent and similar shapes. Regular shapes. Some shapes are always similar. For example, all squares are similar because every square is the same shape.

Similarity in maths involves shapes that have the same proportions but different sizes. At GCSE level, students learn to calculate lengths of similar shapes, apply scale factors to areas and volumes, and solve problems involving similarity. Core level focuses on finding corresponding lengths, while Extended covers relationships between lengths ...

Similarity between triangles is a weaker form of congruence (the triangles have the same shape but are sized differently); however, this flexibility grants us much power in mathematics. The corresponding angles between similar triangles are equal, and the corresponding sides are proportional. We can think of one similar triangle as an ...
The symbol for expressing similar figures is the same symbol for congruence i.e. “\(∼\)” but similarly does not mean the same in size. When the ratios of the corresponding sides are equal, the shapes are considered similar, that is, when dividing each set of corresponding side lengths, the number obtained is the scale factor.
Similar Shapes. Similar shapes are related by a scale factor. This scale factor can be an integer (a whole number) or a fraction. To identify the scale factor, compare two matching sides on the similar shapes and divide the larger side by the smaller side. For example, divide 9 cm (largest triangle) by 6 cm (smallest triangle) to find the scale ...
Similarity What are similar shapes? Two shapes are similar if they have the same shape and their corresponding sides are in proportion. One shape is an enlargement of the other How do we prove that two triangles are similar? To show that two triangles are similar you need to show that their angles are the same. If the angles are the same then corresponding lengths of a triangle will ...
The similar shapes in mathematics are those in which the first one is a proportional enlargement of the other. Scale Factors: When two shapes are similar and connected by a scale factor, denoted as ‘k’: In equivalent areas, areas are connected with an area factor ‘k 2 ‘. Equivalent volumes are characterized by the volume factor k 3.
