Answer:
Step-by-step explanation:
Black Triangle
Rotate the triangle around the origin 90° counterclockwise.
(x, y) → (-y, x)
A(2, 5), B(-7, 5) C(-3, -2) →A'(-5, 2), B'(-5, -7) C'(2,- 3)
Blue Triangle
Rotate the triangle around the origin 180° counterclockwise.
(x, y) → (-x, -y)
A(2, 5), B(-7, 5) C(-3, -2) →A'(-2,-5), B'(7,- 5) C'(3, 2)
Green Triangle
Rotate the triangle around the origin 270° counterclockwise.
(x, y) → (y, -x)
A(2, 5), B(-7, 5) C(-3,-2) →A'(5, -2), B'(5, 7) C'(-2, 3)
Orange Triangle
