- Foundation tier unit 10 check in test Non-calculator Q1. Here are some triangles drawn on a grid. Two of the triangles are congruent. Write down the letters of these two triangles. Q2. Here is a shape drawn on a grid. On the grid, draw an enlargement of the shape with scale factor 3
- 2-58. Casey decided to dilate her favorite letter: C, of course! She dilated several “C”s using a copy machine. The scale factor, or zoom, tells the copier how much to dilate the figures or text on the paper. For example, if Casey sets the zoom on a copy machine to 200%, that is the same as a scale factor of 2.

Here is a triangle. The perimeter of the triangle is 10 cm. Angle A = 40°. The triangle is enlarged by a scale factor of 3 (i) Write down the perimeter of the enlarged triangle. (ii) Write down the size of angle A in the enlarged triangle. (2)
- factor of k, then the areas will be multiplied by a scale factor of k² and the volumes will be multiplied by a scale factor of k³. For example, if the lengths are enlarged with scale factor 4, then the areas will be enlarged with scale factor 16 and the volumes will be enlarged with scale factor 64.
the coordinates of the triangle after a dilation with a scale factor of 4. (x,y) (kx,ky) enlargement (0,0) ... enlarged or reduced by the scale factor .
- Triangle A sides lengths = 10 m, 12 m, 5 m Triangle B side lengths = 20 m, 24 m, 10 m The ratio of Triangle B to Triangle A. 20 10 2 24 12 2 10 5 = = = 2 All sides are proportional with a scale factor of 2. So Triangle A and Triangle B are proportional.
Determine the scale factor for each pair of similar figures in problems 1 through 4. 1. Original New 2. Original New 3. Original New 4. Original New 5. A triangle has sides 5, 12, and 13. The triangle was enlarged by a scale factor of 300%. a. What are the lengths of the sides of the new triangle? b.
- The scale factor is found by dividing a length of a side of the enlarged shape to the length of the corresponding side of the original shape. When there is a negative scale factor, the enlarged shape is turned upside down. Care needs to be taken when finding the corresponding lengths. How to Describe an Enlargement with a Negative Scale Factor ...
Feb 06, 2017 · When you're discussing area of things in the real world, often the scale factor is intended to relate one area to another. In geometry class, we usually think of scale factor as applying to linear measures. If the linear measures of your parking lot have increased by a factor of 3, then the new area is (3^2)*9600 yd^2 = 86,400 yd^2.
