ACT SAT Prep How to determine the perimeter of a triangle using similar triangles

👉 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...

In this video, the teacher explains how to determine if two triangles are similar under dilation. They review the properties of dilation and similar figures, such as proportional corresponding sides and congruent corresponding angles.

This video lesson introduces dilations. Dilations are a transformation that changes the size of a figure by enlarging it by a scale factor greater than one or by reducing it by a scale factor less than one. Real world examples are...
