Similar Figures 2

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

To find the missing side of similar figures, set up a proportion using the lengths of the corresponding sides of the figures.

If two triangles are similar, their corresponding angles are equal.

The scale factor is the ratio of the lengths of two corresponding sides of similar figures.

This means that for every 2 units in one figure, there are 3 units in the other figure.

You can calculate the height of an object by using the properties of similar triangles, often involving a mirror or a shadow.

The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths.

The scale factor is 4:6 or simplified to 2:3.

A proportion is an equation that states that two ratios are equal.

The perimeter of the larger figure will be four times the perimeter of the smaller figure.
