Question

Triangle RST is rotated 270° clockwise about the origin to create triangle R'ST. What are the coordinates of the vertices of triangle R'S'T? Select the correct coordinates from each drop-down menu.

Answer 1

The coordinates of the vertices of triangle R'S'T are R'(8, -3), S'(3, -6) T'(-3, 3)

What are the coordinates of the vertices of triangle R'S'T?

From the question, we have the following parameters that can be used in our computation:

The triangle

Where, we have

R(3, 8), S(6, 3) T(3, 3)

The rule of rotation 270° clockwise about the origin is

(x, y) = (y, -x)

using the above as a guide, we have the following:

R'(8, -3), S'(3, -6) T'(-3, 3)

Hence, the coordinates of the vertices of triangle R'S'T are R'(8, -3), S'(3, -6) T'(-3, 3)
