- Given Triangle ABC with A(2, 3), B(0, 6), and C(2,6). Write down the coordinates of the image after the following composition; reflection over the line y = -x
followed by a rotation of 90 degrees clockwise.
A”( – 3, 2), B”( – 6, 0), and C”( – 6, 2)
(I don’t get numbers 2-4)
- Given a triangle ABC with A(2, 3), B(0, 6), and C(2,6). Determine if the image A”B”C” is congruent to it’s pre-image ABC after the following transformation;
dilation of scale factor 1, rotation about the origin of 180 degrees, and a reflection over the line y = -1. Explain your answer.
- Given triangle ABC with A(2, 3), B(0, 6), and C(2,6). Identify the coordinates of A’B’C’ after a dilation centered at the origin having a scale factor of 2.
- Triangle ABC with A(2, 3), B(0, 6), and C(2,6). Find the area of triangle ABC and its image after a reflection in the origin. What do you notice about the area of
the image and its pre-image? Explain
