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 . The angles are all 90^o

Understanding congruence and similarity forms an integral part of geometry. Grasp these key concepts and practice identifying and proving shapes as congruent or similar, enhancing your skills for more advanced geometry topics.
To check if shapes are similar, compare the angles and lengths of the shapes. Corresponding angles in similar shapes are equal. Use a protractor to measure the angles if they’re not given. Corresponding sides in similar shapes are in the same ratio. This is known as the scale factor.
