A regular pentagon can always be drawn through any two given points with those two points as any two vertices of the pentagon. (Diagonals of a pentagon connect two vertices which are not next to each other.)
The five interior angles of a regular pentagon are all 72º. For each angle to be closed, one of the arms must travel through 360 - 72 degrees. So the exterior angles of a regular pentagon are 360 - 72 = 288º
Five. One line going from each of the corners, through the centre and through the mid point of the opposite side. Assuming it is a regular pentagon where all sides and angles are equal.
No. The diagonal through a rectangle can be computed via the Pythagorean theorem: c2 = a2 + b2 where c is the diagonal length and a and b are the horizontal and vertical lengths of the rectangle.

yes Start with a regular pentagon and position it so that the horizontal line is at the bottom, and one vertex forms the apex. Select the two vertices that are part way to the apex. Move them both in opposite directions. The resulting figure will be a pentagon whose only line of symmetry is the vertical through the apex.

60.28 is the length of the diagonal, got through Pythagoras' Theorem.

A circle with a diagonal line through it is commonly used as a symbol to represent "no" or "not allowed." It is often used in signage to indicate that something is prohibited or unavailable.
Isosceles
It is the 'equals' sign with a diagonal slash through it.
The symbol is a zero with a diagonal line through it.
This is an equals sign with a diagonal line through it ≠ .
