Using a set of points to determine if two triangles are similar to each other
👉 Learn how to determine whether two triangles are similar given the coordinate points of the vertices of the triangle. Two triangles are said to be equal when the corresponding angles of the triangles are congruent (equal) or when the corresponding side lengths are proportional. When given the coordinate points of the vertices of a triangle, we can use the distance formula to obtain the side lengths of the triangle and hence determine if the side lengths are proportional.

Corrections:
5:00 The proportion AC/AE is 2/8, not 2/4. So, yes, the two triangles are proportional with each other.
