Point $A$`A` on the plane is to undergo two successive transformations.

a

First plot point $A'$`A`′, which is the result when point $A$`A` is translated $3$3 units left.

b

Now plot point $A''$`A`′′, which is the result when point $A'$`A`′ is rotated $90^\circ$90° clockwise about the origin.

Represent transformations as geometric functions that take points in the plane as inputs and give points as outputs. Compare transformations that preserve distance and angle measure to those that do not.

Develop definitions of rotations, reflections, and translations in terms of points, angles, circles, perpendicular lines, parallel lines, and line segments.

Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure. Specify a sequence of transformations that will carry a given figure onto another.
