For two figures to be similar, they must be the same shape, not necessarily the same size. They must also follow theses two rules: 1., They must have the same exact angles in the same places, and 2., their sides must grow in proportion. That means that when one figure is bigger than the other, it can't be taller but super skinny, or taller but super wide. Think of when your mom or dad buys your school photos. There is the wallet size, and then you've got your huge poster size. The people who take and adjust the pictures have to make sure that when they grow or shrink the pictures, they don't end up looking like your reflection in the fun house mirror. Each side must grow or shrink at the same rate. For example, a triangle with side 1 being 2 inches long, side 2 being 3, and side 3 being 4 inches long. The similar figure (has to be another triangle) could be 4 inches long for side 1, 6 inches long for side 2, and 8 inches long for side 3. It would be twice as big. You see what I mean? So for two figures to be similar, they must be the same shape, have the same angles, and grow in proportion. P.S. in case your wondering, congruent figures are automatically similar- times one!

What makes to two figures similar?
When they have the same interior angles but different side lengths
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.
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.
Can congruent figures be similar and can similar figures be congruent?
Congruent figures are always similar. However, similar figures are only sometimes congruent.

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).
Can two figures be congruent but not similar?
no because if they are conmgruent then they are similar
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

Similar figures.
What is the definition of a scale factor?
The ratio of any two corresponding similar geometric figures lengths in two . Note: The ratio of areas of two similar figures is the square of the scale factor. The ratio of volumes of two similar figures is the cube of the scale factor. .... (: hope it helped (: .....
What is the difference between similar and congruent?
Congruent means two figures have exactly the same shape and size. If the shape is identical, but not the size , two figures are similar.
