Question

A triangle has vertices at R(1, 1), S(–2, –4), and T(–3, –3). The triangle is transformed according to the rule R0, 270°. What are the coordinates of S'?

(–4, 2)
(–2, 4)
(2, 4)
(4, –2)

Answer 1

(-4,2)

Explanation:

Knowing that/Given that:

The vertices of the triangle are rotated about the origin by 270° counter-clockwise.

In Addition, This transformation changes the co-ordinate (x,y) to (y,-x).

Before (x,y) After ( y, - x)

Vertices New vertices after 270° rotation

R= (1,1) R' = (1,-1)

S= (-2,-4) S' = (-4,2)

T= (-3,-3) T' = (-3,3)

Hence, the answer is (-4,2)
