Question 1
What is the correct matrix form for a 2D translation?
- A) [ 1 0 tx; 0 1 ty; 0 0 1 ]
- B) [ 0 0 0; 0 0 1; 0 0 1 ]
- C) [ 1 1 0; 0 1 1; 0 0 1 ]
💡 Hint: Look for the necessary components to move points horizontally and vertically.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
