Similar triangles are triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other. Here are the key points:Definition:Two triangles are considered similar if they have the same shape but are of different sizes.Mathematically, if two triangles are similar:Their corresponding angles are congruent (equal).Their corresponding sides are proportional.Visual Representation:Imagine two triangles that look alike but may be scaled differently. These are similar triangles.For example, all equilateral triangles are always similar because they have the same shape.Conditions for Similarity:Corresponding angles of both triangles are equal.Corresponding sides of both triangles are in proportion to each other.
