Properties of similar triangles

Triangles are similar if they have the same shape,but not necessarily the same size.
Properties of similar triangles
The corresponding angles are the same
The corresponding sides are in proportion
We can prove triangles are similar by:
Angle Angle ( two angles congruent to two angles of another triangle)
Side Side Side ( ll three sides in proportion to all three sides of another vtriangle)
Side Angle Side ( two proportional sides with congruent angle in between)

The video "Similar Properties" reviews these properties and provides examles.
