Similarity

When they have the same shape, but different sizes

Use similarity to find unknown side lengths!

Triangles are similar when they have matching angles

This is a Pre-Algebra lesson on Scale and Similarity.

This lesson will look at an example involving graphing. The given information will assist in learning how to graph a parabola in vertex form with transformations and horizontal compression. This lesson will give a step by step explanation to better explain the concept .

Congruent & Similar Shapes

Transformations in the Coordinate Plane : Translation & Reflection by Mr Pineault

Two figures that have the same shape are said to be similar. When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

A triangle whose three angles are in the ratio 1 : 2 : 3 and measure 30°, 60°, and 90°.
