Question

Polygon ABCD is drawn with vertices at A(1, 5), B(1, 0), C(−1, −1), D(−4, 2). Determine the image vertices of B′ if the preimage is rotated 180° counterclockwise. B′(0, −1) B′(0, 1) B′(−1, 0) B′(1, 0)

Answer 1

There is a polygon ABCD is drawn with vertices at A(1, 5), B(1, 0), C(−1, −1) and D(−4, 2)

Step-by-step explanation:

Answer 2

Given:

There is a polygon ABCD is drawn with vertices at A(1, 5), B(1, 0), C(−1, −1) and D(−4, 2)

Required:

We want to determine the image vertices of B′ if the preimage is rotated 180° counterclockwise

Step-by-step explanation:

First we draw a polygon

Now to rotate 180 degree counterclockwise means to find the reflection thwough respective axis

Here for point B, the respective axis is y-axis so the reflection about y-axis of point B is B'(-1,0)

Final answer:

B'(-1,0)
