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'?
Answers
Given :-
- 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°.
To Find :-
- What are the coordinates of S' ?
Solution :-
it is given that, the vertices of the triangle are rotated about the origin by 270° counter-clockwise.
So,
This transformation changes the coordinate (x , y) to (y , -x).
Therefore, we get,
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 coordinates of S' are (-4 , 2).
