Question

A triangle has vertices at A(1,3), B(4.2), and C(3,8). Which transformation would produce an image with vertices A(3, -1), B'(2 - 4), C'(8, -3)?A.) A rotation 90' clockwiseB.) A rotation 90' counterclockwisec )A reflection over the x-axisD )A reflection over the y-axis

Answer 1

First, let's make a sketch to better understand the situation

We can see that the triangle has been rotated 90 ° to the right, that is, clockwise.

So, the correct answer is letter A

Why D is not the correct option:

When we make a rotation on the y axis, the following happens,
