Challenge Problems
Push your limits with advanced challenges
A triangle has vertices at points (1, 1), (5, 1), and (3, 4). How would you perform a scaling operation that doubles the size of the triangle?
💡 Hint: Think about how scaling affects both x and y coordinates.
If you were to rotate a point (4, 5) by 90 degrees counter-clockwise about the origin, what would be its new coordinates?
💡 Hint: Revisit the rotation transformation matrix and focus on the trigonometric values for 90 degrees.
