If to polygons are similar how can you find the scale factor?
You divide a length of one polygon by the corresponding length in the other polygon. Any length will do, as long as you use the corresponding length in both.
What is the difference between scale factor and scale ratio?
if two polygons are similar, then the ratio of the length of 2 corresponding sides is called a scale factor
The scale factor of a figure is 1.8 One side of the larger figure is 12cm How long is the corresponding size of the smaller figure?
At a scale of 1.8 to 1, the corresponding length on the smaller figure is 6 2/3 cm (6.66 cm) 12 cm is approximately 1.8 times 6.66 cm
What are the relationship between the area scale factor and the side length scale factor of similar figures?
The area scale factor is the square of the side length scale factor.
What are some methods that can prove triangles congruent?
SSS - Side-Side-SideAll three corresponding sides of the triangles have the same length AAS - Angle-Angle-Side; ASA - Angle-Side-AngleTwo corresponding angles are equal and a corresponding side is equal SAS - Side-Angle-SideTwo corresponding sides have the same length and the enclosed angle is the same. Note: it is important that the angle is the one between the corresponding sides of equal length.RHS - Right_angle-Hypotenuse-SideIn a right angled triangle the hypotenuse and a corresponding side must be equal.

If to polygons are similar how can you find the scale factor?

What is the ratios of a length on a scale drawing to the corresponding length on the real object?
The scale factor.
What is the scale factor of 0.8?
When two similar shapes have a scale factor of 0.8, every length of the second is 0.8 times the corresponding length of the first.
How can you determine the scale factor of a dilation by looking at a segment and its image?
Every part of the original scales by the same scale factor. By using a segment of the original you will determine the scale factor by dividing the length of the image by the length of the original.
What is the name for the ratio of the length of one side of a figure to the length of the corresponding side of a similar figure?
scale factor
What are similar solids?
similar shapes have corresponding angles that are equal. Also, any length in one shape is equal to the scale factor times the corresponding length in the other shape.
How is a scale factor related to scale drawings?
The scale factor of a scale drawing is the ratio of any length in the drawing to the true corresponding length in the "real" object.
How do you find a scale factor of a triangle?
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.
