Section Warm-Up
In this section, we are going to continue studying transformations. Before we look at two more transformations, let’s review what was taught in the first lesson.
Think & Click: Section Warm-UpComplete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
Triangle ABC has vertices at A (-4, 1), B (0, 5) and C (3, -5).
1. What are the coordinates of triangle A’B’C’, which is a translation of triangle ABC 2 units to the left and 3 units up?
A’ (-6, 4), B’ (-2, 8) and C’ (1, -2)
2. What are the coordinates of triangle A’B’C’, which is a reflection of triangle ABC through the x-axis?
A’ (-4, -1), B’ (0, -5) and C (3, 5)
3. What are the coordinates of triangle A’B’C’, which is a reflection of triangle ABC through the line y = x?
A’ (1, -4), B’ (5, 0) and C’ (-5, 3)
