Every pentagon, regular or not, has five interior angles and five exterior angles.
10. or 45. depending on if we're connecting them to adjacent corners or to every other corner
In geometry, "regular" means all the sides are the same (and all angles the same). A regular pentagon has all 5 sides the same. Some pentagons have every side different; other irregular pentagons have 2, 3, 4, or 5 sides the same.
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
It is a polyhedron with a pentagonal base. To every side of the pentagon are attached triangles that meet at a single point in a plane higher than the pentagon (if it is a skew pyramid, the apex will not be above the pentagon).

No. But if you restrict yourself to regular pentagons, then all regular pentagons are similar.
Every pentagon, regular or not, has five interior angles and five exterior angles.
A pentagon has 5 sides.A regular pentagon has every side the same length.Perimeter = 5 x 3s= 15 s(whatever unit a s is, other than a second.)
You can't have a rectangular pentagon. Perhaps you mean regular? In any case every pentagon has 5 sides ("penta" = "five")
Not necessarily. Every side of a regular pentagon is the same length, but there is an infinite variety of irregular pentagons in which no two sides are the same length.

A regular pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon.An irregular pentagon may have none or 1 line of symmetry.

108 degrees The sum of all interior angles of a polygon is equal to the following: 180n-360, where n is the number of sides. For n=5, the total of all of the angles is 180*5-360=900-360=540. Since every angle in a regular polygon, each interior angle of a regular pentagon is 540/5=108 degrees.
