Enlargement and Scale Factors

What is the scale factor used to enlarge triangle A in the first example?

• 2

• -2

• 3

• -3

Where is the center of enlargement located in the first example?

• (0, 0)

• (4, -3)

• (1, 1)

• (2, 2)

How do you determine the new position of a point after enlargement?

• Subtract the scale factor from the coordinates

• Divide the coordinates by the scale factor

• Multiply the change in coordinates by the scale factor

• Add the scale factor to the coordinates

What is the purpose of checking the alignment of points through the center of enlargement?

• To verify the scale factor

• To find the center of enlargement

• To calculate the new coordinates

• To ensure the enlargement is correct

What is the scale factor used in the second enlargement example?

• 2

• -2

• -3

• 3

Where is the center of enlargement located in the second example?

• (2, 2)

• (4, -3)

• (0, 0)

• (1, 1)

What is the result of multiplying a change in coordinates by a negative scale factor?

• The point moves in the same direction

• The point moves in the opposite direction

• The point moves to the origin

• The point does not move

What is the scale factor used in the third enlargement example?

• -1.5

• 1.5

• -0.5

• 0.5

Where is the center of enlargement located in the third example?

• (2, 2)

• (1, 1)

• (4, -3)

• (0, 0)

What happens to the coordinates when multiplied by a scale factor of -1.5?

• They double

• They remain the same

• They halve

• They reverse direction and increase by 1.5 times
