A heptagon has 4 diagonal lines and 7 sides and it has 2 congruent diagonal lines and 2 congruent triangles
Not many. Depending on how you write, the letters L, O, Q, and X can have diagonal lines of symmetry.

1 its from the "right angle point" on a diagonal to the center of the longest line.None normally but if it's an isosceles right angle triangle it will have 1 line of symmetry.
None
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.

There are four diagonal lines in a hexagon.

Diagonal lines are used for many things like art and designs. They can be used for buildings.
