Why is true that the diagonals of a pentagon intersect on an one vertex?

There is no reason because the statement for which you are seeking a reason is patently FALSE. Consider a pentagram, for example.

Are all diagonals of a regular pentagon congruent?
True
The point at which the diagonals of a parallelogram intersect is. equdistant from the four vertices?
The statement is no true.
Can the altitudes of a right triangle intersect in the interior of the triangle?
No. Only 2 altitudes can intersect at a point. * * * * * True but even they do not meet in the interior. The altitudes of a right angles triangle meet at the right angled vertex. The vertex is at the boundary of the triangle, not in the interior.
What is true about the Diagonals of a regular pentagon?
72 degrees unless you are making a pentagon then you would cut the boards at 1/2 of 72 degrees or 36 degrees. the secret is to remember there are 360 degrees in total. just divide that by whatever equal sided shape you need.
Is it true that diagonals of a parallelogram bisect the opposite angles?
It is true only when the parallelogram is in the form of a rhombus, and thus the two diagonals are perpendicular to each other.

What is true of the diagonals of a rectangle that isn't true of the diagonals of a parallelogram?
They are of equal length.

Is it true that a picture of a pentagon displays all the lines of symmetry for the pentagon?
TRUE!
Is it true triangles have no diagonals?
Yes.
What is true about the diagonals in an isosceles trapezoid?
The 2 diagonals in an isosceles trapezoid are of equal lengths
If two lines intersect they intersect in an infinite number of ponits true or false?
false they intersect at a single point
Are a trapezoid's diagonals ever perpendicular?
Yes, they can be. Here is an example to see how this is true. Construct two perpendicular lines AB and CD that intersect at a point O. Let AO = CO, BO = DO and AO ≠ BO, then ABDC forms an isosceles trapezoid. If the lines are not perpendicular, then also ABDC is an isosceles trapezoid and it has perpendicular diagonals.
The diagonals of a rhombus are perpendicular to each other true or false?
True
Is it true that diagonals of a parallelogram bisect the opposite angles?
It is true only when the parallelogram is in the form of a rhombus, and thus the two diagonals are perpendicular to each other.
