define reflection symmetry

• symmetry where one half is the reflection of the other half

• shape still looks the same after being rotated

• polygon with four sides

what is rotational symmetry?

• shape still looks the same after being rotated

• when a triangle has 2 equal sides

• can be translated so the end result is exactly the same
