Challenge 1 Hard

You have triangle XYZ with vertices X(1, 2), Y(1, 5), Z(4, 2). Reflect it across the line x = 2. What are the new coordinates?

💡 Hint: Remember, only the x-coordinates will change!

Challenge 2 Hard

Given the rectangle with vertices A(0, 0), B(2, 0), C(2, 3), D(0, 3), reflect it across the line y = 1. What are the new coordinates?

💡 Hint: Keep the x-coordinates the same and manipulate the y-coordinates.
