Example Questions
Example Question #11 : Understand Transformations In The Plane
What is the result of rotating the point 
Rotating a point
geometrically in the plane about the origin 
Thus, since our initial point was
we negate both coordinates to get
as the rotation about the origin by 
Example Question #1 : Rotations
Examine the figures in the above diagram. Figure 2 is the result of performing which of the following transformations on Figure 1?
The diagram below superimposes the two figures:
The transformation moves the black diagonal to the position of the red diagonal, and, consequently, points 
Example Question #1 : Rotations
Rotate the above figure 
None of the other choices gives the correct result.
A counterclockwise rotation of 
In the right figure, the question mark has been turned one-eighth of a complete turn counterclockwise. This is the correct orientation.
Example Question #61 : Measurement And Geometry
Let 
Rotate the above hexagon 
A 
The image of 
Now, locate the midpoints 
It can be seen that the image of 
Example Question #21 : Understand Transformations In The Plane
In the above octagon, let 
Rotate the above octagon 
A 
The image of 
Now, locate the midpoints 
The image of 
Example Question #61 : Measurement And Geometry
Rotate the above hexagon 
A 
The image of 
Now, construct 
The image of 
Example Question #1 : Rotations
Between 6:15 and 6:40, the minute hand of a clock undergoes which of the following clockwise rotations?
Between 6:15 and 6:40,
minutes elapse.
The minute hand of a clock rotates one complete 
Example Question #2 : Rotations
Over the course of 20 minutes, the hour hand of a clock undergoes which of the following rotations?
The hour hand of a clock makes one complete 
minutes.
Therefore, over the course of 20 minutes, the hour hand rotates
Example Question #1 : Rotations
Over the course of one minute and forty seconds, the minute hand of a clock undergoes which of the following clockwise rotations?
The minute hand of a clock rotates one complete 
Over the course of 1 minute 40 seconds - or, since one minute is equal to 60 seconds, 
Example Question #1 : Rotations
Examine the figures in the above diagram. The figure at right is the result of performing which of the following transformations on the figure at left?
A 
A

A
Examine the figure below:
If we connect the horizontal line with the line along the rotated nine at right, we see that it is the result of a one-third turn clockwise; the angle between them
