What is rotation in 2D transforms?

• Process of moving an object or shape in a straight line in a two-dimensional plane.

• Process of changing the size of an object or shape in a two-dimensional plane.

• Process of rotating an object or shape around a fixed point in a two-dimensional plane.

What is scaling in 2D transforms?

• Changing the color of an object by applying a color transformation matrix.

• Changing the size of an object by multiplying its coordinates by a scaling factor.

• Changing the position of an object by adding a translation vector.

What is the result of translating an object 5 units to the right and 3 units up?

• Translate the object 5 units to the left and 3 units down by subtracting 5 from the x-coordinate and adding 3 to the y-coordinate.

• Translate the object 5 units to the right and 3 units down by adding 5 to the x-coordinate and adding 3 to the y-coordinate.

• Translate the object 5 units to the left and 3 units up by subtracting 5 from the x-coordinate and subtracting 3 from the y-coordinate.

• Translate the object 5 units to the right and 3 units up by adding 5 to the x-coordinate and subtracting 3 from the y-coordinate.

What is the result of scaling an object by a factor of 2?

• The result of scaling an object by a factor of 2 is that the object will be twice as large as its original size.

• The result of scaling an object by a factor of 2 is that the object will be the same size as its original size.

• The result of scaling an object by a factor of 2 is that the object will be three times as large as its original size.

• The result of scaling an object by a factor of 2 is that the object will be half its original size.

What is the result of reflecting an object across the x-axis?

• Rotating the object 90 degrees

• Stretching the object horizontally

• Flipping the object vertically

• Inverting the object colors
