How do you find the dimensions of a figure if you know the dimensions of a similar figure?
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides.
What information does the scale factor give us about two similar figures?
The ratio of the lengths of their corresponding sides.
How do you solve your math problems dealing with similar figures?
Any two corresponding sides in two similar figures have a common ratio called the scale factor. Since the figures are similar, the ratios of the lengths of corresponding sides of the figures are equal. 1. Match a side of both figures, 2. write the proportions 3. substitute the values 4. Write the cross product 5. Divide both sides by a common factor 6. simplify 7. Convert improper fraction into mixed number
In geometry what does similar mean?
In geometry, similar refers to two figures that have the same shape but may differ in size. Specifically, similar figures have corresponding angles that are equal and corresponding sides that are proportional in length.
What dose it mean for two shapes to be similar?
Two shapes are similar when the sides of one are directly proportional to the corresponding sides of the other. That all the corresponding angles are equal.
How are corresponding side lengths two similar figures related?
Corresponding sides of similar figures are proportional.
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.
How can you determine mathematically if two figures are similar?
If the two figures are the same shape. Also if the ratios of the lengths of the corresponding sides are equal.
If two rectangles are similar then the corresponding sides are?
If two rectangles are similar, they have corresponding sides and corresponding angles. Corresponding sides must have the same ratio.

What information does the scale factor give us about two similar figures?
The ratio of the lengths of their corresponding sides.
When are two similar figures also congruent?
If the scale factor is 1. That is, if a pair of corresponding sides are the same length.
What is alike and different about similar and congruent figures?
If two figures are similar or congruent, each angle of the first figure is the same as the corresponding angle of the second figure.In similar figures, the ratio of each side in the first figure to the corresponding side in the second figure is a constant. If the figures are congruent, that ratio is 1: that is, the corresponding sides are of the same measure.
What it is called when something is the same shape but not necessarily the same size Corresponding sides are proportional?
In that case, the two figures are "similar".
What are the similarities of geometry figures?
Two geometric shapes are similar if they differ only in their size. For polygons this requires that the corresponding angles of the two polygons are congruent and that the ratio of their corresponding sides is the same.

Definition of Congruent Figures?
The Definition of Congruent Figures (which is a proof) says that if two figures have corresponding sides congruent and corresponding angles congruent, then the figures are to be congruent.
