Question 1 - Think and Reflect (Page 11) What has remained the same and what has changed with this reflection? Let’s do it one by one What remained the same The side lengths of the triangle (5,√29, and √40 units) remain exactly the same. Because the side lengths are identical, the overall size, shape, and area of the triangle are completely preserved. What changed The x -coordinates of all the points changed from positive to negative (for example, A is at 𝑥=3, but A^′ is at 𝑥=−3 ). The triangle's physical location and visual orientation on the grid have also flipped.
