Two two-dimensional polygons are if their side lengths are proportional?

similar


Two polygons are similar if the corresponding angles are congruent and the corresponding sides are?

Proportional.


Do two polygons which are similar have the same shape?

Similar polygons are polygons for which all corresponding angles are congruent and all corresponding sides are proportional. From this definition we can say they have the same shape.


What are the two main properties of similar of polygons?

Their sides are proportional and their interior angles are the same


Can you have two polygons having corresponding side lengths that are proportional and can you conclude that the polygons are similar?

No. You could, for example, have a square and a rhombus with sides twice as large.


Which polygons are not similar?

Any two polygons with a different number of sides are not similar.


Are two rhombuses always-sometimes or never similar?

Sometimes. Remember, in order for two polygons to be similar, their angles must be congruent, and their corresponding sides must be proportional. In a rhombus, it is always possible for the angles to differ.


Two polygons with same shape not size?

The polygons are said to be similar.


How can you tell if two polygons are the same?

Two polygons are similar if and only if the corresponding angles are congruent


Must the corresponding angles of two similar regular polygons be equal?

All angle of two similar regular polygons must be equal.


The corresponding sides of two similar regular polygons must have equal lenghts?

Yes, the corresponding sides of two similar regular polygons must have equal lengths. This is because both the polygons are similar, which means that since they are also polygons, they must have equal lengths.
