You need to find the perimeter of one by adding together the lengths of all its sides. The perimeter of the similar shape is the answer multiplied by the similarity ratio.

What does the scale factor between two similar figures tell you about the perimeter?
The perimeter will scale by the same factor.
What does the scale factor between two similar figures tell you about the given measurement perimeters?
Perimeter will scale by the same factor. Area of the new figure, however is the original figures area multiplied by the scale factor squared. .
Which polygon has the greater perimeter an rectangle or a pentagon?
The answer will depend on how big the two figures are!
Can a reflection be used to determine if figures are similar?
yes. if the two figures are the same size and shape, then they are similar
Can two figures be congruent but not similar?
no because if they are conmgruent then they are similar

Is it true that the greater the perimeter the greater the area?
No, in general that is not true. For two similar figures it is true. But you can easily design two different figures that have the same perimeters and different areas, or the same area and different perimeters. For example, two rectangles with a different length-to-width ratio.
Describe at least two ways of finding a missing side length in a pair of similar figures?
You would look at the side lengths and the scale factor to find a pair of similar figures :)

What are features that make two planar figures similar?
If all angles of two polygons are the same the figures are similar (irrespective of rotation).
How are corresponding side lengths two similar figures related?
Corresponding sides of similar figures are proportional.
Can a reflection be used to determine if figures are similar?
yes. if the two figures are the same size and shape, then they are similar
Can two figures be congruent but not similar?
no because if they are conmgruent then they are similar
How can you tell if two figures are similar?
Two figures are similar if: - The measures of their corresponding angles are equal. - The ratios of the lengths of the corresponding sides are proportional.
If a diameter of the semicircle is 14cmfind its perimeter?
Perimeter = Circumference/2+Diameter Perimeter = (pi*14)/2+14 = 35.99114858cm or 36cm correct to two significant figures.
If two figures are similar then are they also congruent?
No. Two figures are similar if they have same shape, and all the angles are equal; but they can have the sides of different sizes. I mean, similar figures may have different sizes, but must have the same shape.
