Challenge Problems
Push your limits with advanced challenges
A rectangle with coordinates (1, 2), (1, 4), (3, 4), and (3, 2) is scaled by factors of (2, 3) along the x-axis and y-axis. What are the new coordinates?
💡 Hint: Apply the scaling factors to each coordinate individually.
Consider a cube centered at the origin with vertices at (-1, -1, -1) and (1, 1, 1). If it is scaled by 2 on the x-axis and 0.5 on the z-axis, what will be the new coordinates for the vertices?
💡 Hint: Calculate new vertex positions considering the scaling for each axis.
