Are two regular polygons always similar?
no.
What are 2 similar pentagons?
Two pentagons that have corresponding angles congruent. First equals the first, second equals the second and so forth.
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.
Are two regular polygons similar if and only if they have the same number of sides?
yes
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.
Are two congruent pentagons either always sometimes and never similar?
If they are congruent they must be similar.
Are pentagons always regular?
Pentagons do not have to be regular. Elongating one side will skew two angles and make them non congruent with the other three, creating an irregular polygon.
Are pentagons congruent?
Some are some are not. Two regular pentagons with one equal side are congruent.
Are two regular polygons always similar?
no.
What are two regular pentagons?
Jasmine drew 2 pentagons Compare the 2 pentagons that Jasmine drew. Tell how they are alike, and identify three ways that they are different.
Are two hexagon always similar to each other?
No. Two regular hexagons are always similar to each other, but two random hexagons are not necessarily similar.
Does the lenght of a side of a regular polygon affect the sum of the interior angle measure?
If you draw two regular polygons, for example pentagons, of two different sizes, the length of the sides will vary between the two pentagons, but the angle between the sides of the pentagons will be the same, therefore the sum of the angles will not change.
Are two regular hexagons are sometimes always or new similar to each other?
always
What are 2 similar pentagons?
Two pentagons that have corresponding angles congruent. First equals the first, second equals the second and so forth.
Are two regular octagons always sometimes or never similar?
never ever ever
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Is a pentagon convex?
A regular pentagon is convex. By taking a regular pentagon and shortening or lengthening one or more sides, an infinite number of possible convex pentagons can be created. A convex polygon is defined as a polygon such that all internal angles are less than or equal to 180 degrees, and a line segment drawn between any two vertices remains inside the polygon. It is possible to have non-convex (concave) pentagons; there are infinite number possible ways to do this, too.
