Polygons that have the same shape but not necessarily the same size?
They are similar
Are congruent polygons similar?
No because they are exactly the same
How do you know if polygons are similar?
If they are the same shape and size
Are polygons congruent if they have the same surface area?
No, not necessarily.
Do two similar polygons have to be congruent?
no, they could be different size but same shape and be similar but not congruent.
Are similar polygons always the same shape?
Yes
Two polygons with same shape not size?
The polygons are said to be similar.
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.
Do similar polygons have the same shape?
Yes and the same angles
Polygons that have the same shape but not necessarily the same size?
They are similar
Are any two regular polygons with the same number of sides similar?
Yes, regular polygons will have all sides equal length, and all angles the same. If two polygons of the same number of sides are 'regular' then those two polygons will be similar (they may be scaled, for example).
Are congruent polygons similar?
No because they are exactly the same
How do you know if polygons are similar?
If they are the same shape and size
How can you tell if two polygons are the same?
Two polygons are similar if and only if the corresponding angles are congruent
What are polygons that have the same shape but not the same size?
They are said to be similar by proportion
What do you call polygons with the same shape but not exactly the same size?
The are similar
Is two regular polygons always sometimes or never similar?
If they have the same nuber of sides (angles) then always. If not then never. So, overall, I suppose the answer is sometimes - depending on the number of sides.
