The only polygon with no diagonal is the triangle.
hypotenuse
The sides of the triangle will always meet at angles such that two of them will appear 'diagonal'. But these are not defined as diagonal lines. There are actually no diagonals intersecting any triangle. Try drawing one and connecting the vertices - it doesn't work and you simply end up tracing over the lines that define the triangle.
None
angles...
No

you talk about how a triangle's line is diagonal.
no but the diagonal divides the square into two equilateral triangles. An equilateral triangle is a triangle that has two sides of the same length
Kitty-corner is another term for diagonal. A right triangle's hypotenuse is on a diagonal. On a keypad, the five is on a diagonal from the nine.
zero

right triangle ( triangles with a right angle)
It is formed by the diagonal of a rectangle
None
x=y is the diagonal line which runs through 0,0 so all you have to do is reflect the triangle on the diagonal line. hop that helps :)
