Translation

A translation is an isometry
Translation Theorem

How is component form written?
<Horizontal, Vertical>

Shows both direction and magnitude
Vector

Can translations also be described as vectors?
yes

Vectors:
What is the part with the arrow called?
Terminal point

Vectors:
What is the part without the arrow called?
Initial point

What is the symbol that you put over top of the letters when showing it's a vector?
__\

What order do you go in to find the component form?
 <Intial Point, Terminal Point>
 <Horiziontal, Vertical>

Turning of an object around a fixed point
Rotation

Can rotations be clockwise and counterclockwise?
Yes

A rotation is an isometry
Rotation Theorem
