Two triangles are said to be similar, if their corresponding angles are equal or their corresponding sides are in proportion.
Two triangles are said to be similar, if their corresponding angles are equal or their corresponding sides are in proportion.
These conditions for similarity of triangles can be explored by increasing/decreasing the length of sides, flipping/rotating the triangles given in this geogebra file.
