In the xy-plane, the coordinates of the vertices of triangle KLM are K (2,1), L(3,5), and M (6,3). What are the coordinates of vertices of triangle K'L'M' that results from rotating 90 degrees clockwise about point K?
K'(-1,2) L'(-5, 3) M'(-3,6)
K'(1,-2) L'(5, -3) M'(3,-6)
K'(2,1) L'(4, -3) M'(6,0)
K'(2,1) L'(6,0) M'(4, -3)
Carlos drew segment CD on a coordinate grid and translated it 3 units to the right to form C'D'. Which statement must be true.
CD and C'D' lie on the same line.
CD and C'D' are parallel to each other
CD and C'D' are perpendicular to each other
CD and C'D' intersect each other, but are not perpendicular
Four students in Mr. Smith's class made observations about transformations. Which student is correct?
Ralph: "The transformation (x,y) -> (x - 4, y + 2) applied to a line segment yields a shorter line segment."
Pavel: "The transformation (x,y) -> (y, -x) applied to a line segment yields another line segment parallel to the first."
Megan: "The transformation (x,y) -> (-y, -x) applied to an angle yields an angle with a greater measure."
Taisha: "The transformation (x,y) -> (x+5, y - 2.5) applied to a circle yields a congruent circle."
