Question

Figure 1 is rotated 90° clockwise around the origin. Which figure is the image of Figure 1?A. Figure 4B. Figure 2c. Figure 3D. Figure 5

Answer 1

The rotated image of figure 1 around the origin is Figure 3

SOLUTION:

The easiest to do this is by counting how many units are the edges away from the axis. since the point of rotation is the origin.

Originally, there are 2 units away from the x and y-axis.

after rotation, the 2 units away from the y-axis will be the 2-units away from the x-axis,

similarly, the 2 units away from the x-axis will be the 2-units away from the y-axis.

Also, originally, the image is in the second quadrant. After 90 degrees rotation clockwise, it should be in the first quadrant.

Using these conditions, we will find the figure that satisfies these conditions.
