A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes.

How do you do scale copies?
To create a scaled copy, we multiply all the lengths in the original figure by the same number. This number is called the scale factor. In this example, the scale factor is 1.5, because , , and . A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.
What is an example of a scaled copy?
A scaled copy is a copy of an figure where every length in the original figure is multiplied by the same number. For example, triangle DEF is a scaled copy of triangle ABC. Each side length on triangle ABC was multiplied by 1.5 to get the corresponding side length on triangle DEF.
What’s a scale drawing?
Definition: Scaled Drawing. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (called the scale).
How do you use scale drawings?
Drawings can be scaled up or down using either a calculator or a scale rule. To scale a drawing using a calculator: divide the measurement by the scale if you want to reduce the drawing in size, or. multiply the measurement by the scale if you want to increase it in size.
What is not a scaled copy?
Copy 1 is a scaled copy of the original triangle.Copy 3 is not a scaled copy of the original triangle. The shape has been distorted. The angles are different sizes and there is not one number we can multiply by each side length of the original triangle to get the corresponding side length in Copy 3.
Is rectangle a scaled copy of rectangle B?
Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B. Rectangle A has length 12 and width 8. Rectangle B has length 15 and width 10.
Is polygon PQRS a scaled copy of polygon ABCD?
Polygon ABCD is a scaled copy of polygon PQRS.
What is the difference between scale and scale factor?
Using Proportions to Find Scale Factor
Proportional means having the same ratio. A scale factor is the ratio of the model measurement to the actual measurement in simplest form. Unlike a scale ratio, the scale factor does not compare different units of measurement.Next, compare the quantities using the same units.
What is scale example?
Scale is defined as a system or series of marks used for measuring or registering. An example of scale is what someone would use to figure out the length of something. An example of scale is what someone would use to find out how much they weigh. noun. 13.
What is a scale drawing Virtual Nerd?
What is a Scale Drawing? Without a blueprint, it would be really hard to construct a building. Without a road map, you’d be lost! Scale drawings make it easy to see large things, like buildings and roads, on paper. Even a GPS uses scale drawings!
What are scaled copies answer key?
A scaled copy is a copy of an figure where every length in the original figure is multiplied by the same number. For example, triangle is a scaled copy of triangle . Each side length on triangle was multiplied by 1.5 to get the corresponding side length on triangle .
What is the purpose of scale drawing and plans?
Scale drawings are a useful tool for any designer, because they can be used to plan, visualize and adjust landscape plans before breaking ground. Scale drawings assign each object the same scale compared to the actual objects.
What is scale architecture?
In very general terms ‘scale’ refers to an item’s size in relationship to something else. For example, the components of a building may be designed so they are at a human scale, ie they are comfortable to use, are functional and anthropometric, or manufacturing can be carried out at scale, rather than for one-offs..
What is a scale factor in math?
Definition of scale factor
A scale factor is the ratio of sizes of two similar figures. For example, the scale factor is 2 for the following two similar figures. The scale factor is 2 because the triangle on the right is two times bigger than the triangle on the left.
How do you identify a scale factor?
The basic formula to find the scale factor of a figure is: Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. This can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.
What is a scale image?
Image scaling is the process of resizing a digital image. Scaling down an image makes it smaller while scaling up an image makes it larger. Both raster graphics and vector graphics can be scaled, but they produce different results.
How do you write a scale?
The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing. Example: this drawing has a scale of “1:10”, so anything drawn with the size of “1” would have a size of “10” in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.
What does a scale of 1 to 5 mean?
“1” and “5” values would represent the polar extremes or anchors on a 5-point, Likert-type response scale. Usually (but not always), “5” is the higher, or preferred, end of the scale options, whereas “1” is the lower end. Usually, verbal anchors are supplied to correspond with response points.
How do you make a scale?
To create a scale, you must know the physical size of the map. Therefore, you must measure the length of the map. For example, if the map is 12 inches in length, partition the map into one-inch increments. Next, look up the specific distance as the crow flies—a straight-line distance—between two locations on the map.
What is the scale factor from rectangle A to rectangle B?
4
The scale factor from Rectangle A to Rectangle B is 4.
