What else can I help you with?
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.
How do you do enlargement?
Viagra
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.
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.
How can you determine whether a dilation's is a reduction or a enlargement?
To determine whether a dilation is a reduction or an enlargement, compare the scale factor to 1. If the scale factor is greater than 1, the dilation is an enlargement, as the image will be larger than the original. Conversely, if the scale factor is between 0 and 1, the dilation is a reduction, resulting in a smaller image. Additionally, you can observe the distances from the center of dilation; if they increase, it's an enlargement, and if they decrease, it's a reduction.

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.
