What are two regular pentagons?

What shapes are on the faces of a dodecahedron?
The shape of the 12 faces of a regular dodecahedron are regular pentagons.
Are all pentagons are similar?
NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
Every pentagon is similar to every other pentagon?
No. But if you restrict yourself to regular pentagons, then all regular pentagons are similar.
Are two regular pentagons similar?
Yes, two regular pentagons are similar. Regular pentagons have the same shape but can differ in size; they both have equal angles of 108 degrees and corresponding sides that maintain a constant ratio. This characteristic of having corresponding angles equal and sides proportional is the definition of similarity in geometric figures.
Is regular polygons also similar?
-- All regular (equilateral) triangles are similar. -- All squares are similar. -- All pentagons are similar. -- All hexagons are similar. . . . etc. Any regular polygon is similar to all other regular polygons with the same number of sides.
How do you put 3 regular pentagons together?
Regular pentagons do not tessellate.
Are two regular pentagons always similar?
Yes they are. All ten angles are 54 degrees.
Are pentagons regular or not regular?
jyf
Do pentagons have perpendicular lines?
Not if they are regular 5 sided pentagons
Are all pentagons similar?
No, similar pentagons (or any polygon for that matter) must have corresponding congruent angles and all sides must be proportional to its corresponding sides. For example, if a square with a triangle on it is a pentagon, then a regular pentagon would not be similar to it (because corresponding angles are not congruent).
How many are regular pentagons?
There are infinitely many regular pentagons - a different one for each value for the length of its side.
Do all pentagons have congruent angles?
Yes providing that they are regular 5 sided pentagons otherwise no if they are irregular pentagons
In a regular dodecahedron opposite faces are what?
Regular pentagons.
