Similar Triangles & Scale Drawings in Geometry - [7-5-1]

In this lesson, you will learn what similar triangles are and how to determine if two triangles are similar. We learn about this topic in geometry, where triangles play a central role, especially right triangles. Two triangles are said to be similar if all three sides are in the same ratio with one another. To determine if the triangles are similar, we compare the corresponding sides and calculate the ratios. If all three ratios are the same, then the triangles are similar.
