Question

A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is rotated 90° clockwise around the origin?

Answer 1

so what do i do?

Answer 2

Now you switch each ordered pair like this:
(x, y) becomes (-y, x)
Do this for each ordered pair

Answer 3

A(1, 5) --> A'(-5, 1)
B(-2, 1) --> B'(-1, -2)
C(0, -4) --> C'(4, 0)

Answer 4

A=-5,1

Answer 5

oh okay thank you so much , this was great help!
