Question

Identify the image of XYZ for a composition of a 190 rotation and a 80 rotation, both about point y

Answer 1

190° rotation = c

80° rotation = a

Explanation:

b = 180° rotation

d = 360° rotation

Answer 2

The correct option is c.

Explanation:

If the direction of rotation is not mentioned, then it is considered as counterclockwise rotation.

It is given that the figure XYZ rotated 190° and a 80° rotation(composition), both about point y.

It means figure is rotated 80° counterclockwise about the point y after that the new figure is rotated 190° counterclockwise about the point y.

`80^(\circ)+190^(\circ)=270^(\circ)`

It means the figure XYZ rotated 270° counterclockwise about the point y.

In figure (a), XYZ rotated 90° counterclockwise about the point y.

In figure (b), XYZ rotated 180° counterclockwise about the point y.

In figure (c), XYZ rotated 270° counterclockwise about the point y.

In figure (d), XYZ rotated 360° counterclockwise about the point y.

Therefore the correct option is c.
