Question

Triangle ABC has vertices A(–2, –3), B(–5, –3), and C(–4, –2). The triangle is rotated 90° counterclockwise around the origin.

A) A’(3, 2), B’(3, 5), C’(2, 4)

B) A’(3, –2), B’(3, –5), C’(2, –4)

C) A’(–3, –2), B’(–3, –5), C’(–2, –4)

D) A’(–3, 2), B’(–3, 5), C’(–2, 4)

Answer 1

B

Explanation:

I took the test

Answer 2

The rule for this rotation is (x, y) converted into (-y, x). So, to find the answer you would make the y negative and switch the values in the ordered pair. A would be (3, -2), B would be (3, -5), and C would be (2, -4). So, your answer would be B. Hope this helps!
