Triangles are similar if they have the same shape, but can be different sizes.
(They are still similar even if one is rotated, or one is a mirror image of the other). Triangles are similar if:
- AAA (angle angle angle)
All three pairs of corresponding angles are the same.
- SSS in same proportion (side side side)
All three pairs of corresponding sides are in the same proportion.
- SAS (side angle side)
Two pairs of sides in the same proportion and the included angle equal.
