What is the measure of rotation about the point B?
A rotation is a transformation that turns the figure about a fixed point.
Mark points P and P'.
Join the points to B and measure the angle of rotation.
The angle of rotation is observed as 70°.
Correct answer : (4)
Which of the following is the rotational image of the given figure?
Solution:A rotation is a transformation that turns the figure about a fixed point.
The figures 1, 2 and 3 are not the rotational images of the given figure.
[Rotation does not change orientation.]
Figure 4 matches with the given figure and is obtained as a result of rotating it.
So, figure 4 is the correct answer.
Correct answer : (3)
