Question 1.
What is the matrix representation of a point in 2D?
Show hintHide hint
Remember how we express coordinates in two dimensions.
Question 2.
Define translation in the context of 2D transformations.
Show hintHide hint
Think about moving a shape along the graph.
3Question 3.
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 ]
Show hintHide hint
Look for the necessary components to move points horizontally and vertically.
4Question 4.
True or False: The order of concatenation in transformations does not matter.
- True
- False
Show hintHide hint
Think about performing two transformations one after the other.
Question 5.
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?
Show hintHide hint
Think about how scaling affects both x and y coordinates.
Question 6.
If you were to rotate a point (4, 5) by 90 degrees counter-clockwise about the origin, what would be its new coordinates?
Show hintHide hint
Revisit the rotation transformation matrix and focus on the trigonometric values for 90 degrees.
