If someone enlarged a drawing by a scale factor of 3 and got 396 cm squared what was the original drawing?
The scale factor is usually stated as a linear enlargement factor. Therefore, the area enlargement factor is the square of the scale factor, in this instance, 9. The area of the original drawing was thus 396/9 = 44 cm2.
Is a transformation that turns a figure to a fixed point?
An enlargement with a scale factor of 0.
What transformation is equivalent to reflection over a point geometry?
Reflection over a point is equivalent to enlargement with the same point as the focus of enlargement and a scale factor of -1.
Are the ratios of all three pairs of corresponding sides of similar triangles equal?
Yes. When a shape is enlarged the scale factor gives the ratio between corresponding lengths of the enlargement and the original.
How do you do enlargement?
Viagra
What information do you need to complete a given shape enlargement?
The scale or enlargement factor.
What is an enlargement with a negative scale factor?
It is a smaller shape on the other side of the centre of enlargement.
Another name for scale?
Enlargement factor.
What type of dilation occurs with a scale factor of 14?
The type of dilation that occurs with a scale factor of 14 is enlargement. Any time the scale factor is larger than 1, it is enlargement.
A dilation is an enlargement if the scale factor is?
greater then 1
What is a negative scale factor?
A negative scale factor is used to produce the image on the other side of the centre of enlargement (scaled to the absolute value of the scale factor).
What effect does the scale factor have on the area of the enlargement?
The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.The area of the enlargement is increased by (sf)2.

What happens to an enlarged image when the scale factor of enlargement is one?
Absolutely nothing. A scale factor of 1 is the same as saying do not change the scale.
Transformation that enlarges or reduces a figure?
Scaling changes the size of a figure. If the scale factor is greater than 1, the figure is enlarged; if the scale factor is less than 1, the figure is reduced. I the scale factor is equal to 1, the figure's size is unchanged. If there is a centre of enlargement, the new figure can be drawn exactly by multiplying the distance of every point from the centre of enlargement, multiplying this by the scale factor and drawing the new point at this distance from the centre of enlargement. (For a polygonal figure, only the vertices need be measured and the lines between the vertices of the original figure drawn in). With a centre of enlargement, the scale factor can be negative. In this case, the distance to the new points is measured on the opposite side of the centre to the original points, so that it is a straight line form the original point, through the centre to the new point.
