NO! Only REGULAR Pentagons. All equilateral triangles are similar!!!
Some are some are not. Two regular pentagons with one equal side are congruent.

If they are congruent they must be similar.
There are infinitely many regular pentagons - a different one for each value for the length of its side.

No. But if you restrict yourself to regular pentagons, then all regular pentagons are similar.
Yes they are. All ten angles are 54 degrees.
Some are some are not. Two regular pentagons with one equal side are congruent.
Regular pentagons do not tessellate.
Jasmine drew 2 pentagons Compare the 2 pentagons that Jasmine drew. Tell how they are alike, and identify three ways that they are different.
-- 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.
Yes, because they will have 5 equal sides and 5 equal angles
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.
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.
