Use a really thick line.
it depend upon the figure.only the can it be said that whether 9 lines can be made form 4 points.

An octahedron has 9 lines of symmetry. These lines can be categorized into three types: four lines that connect the midpoints of opposite edges, six lines that connect opposite vertices, and one line that runs through the centers of opposite faces. This symmetry reflects the octahedron's balanced and regular geometric structure.

draw lines and connect them
It depends on where the dots are located.

To connect 9 dots with 4 lines, you must think outside the box. The key is to draw lines that extend beyond the boundaries of the dots. Start by drawing a line that goes through the first three dots in an L shape, then continue the line outside the dots to connect the remaining dots. This unconventional approach allows you to connect all 9 dots with just 4 lines.

Assuming the point is (9, -4), the equation is y = -4.

On a quick estimate, I would think 18, 9 for each interior side and another 9 for each interior angle. * * * * * A nonagon has only 9 lines so the above answer is nonsense. With 9 lines you can have at most 4 pairs of parallel lines (and one not parallel to any). Or you could have a concave nonagon with 1 pair, 1 triplet and 1 quartet of parallel lines, or some other combination.

I get 9 triangle with fewer than 9 lines. Draw a square: ABCD (4 lines) Draw the diagonals AC, BD (2 lines) which meet at X in the centre. On a separate part of the page, draw triangle PQR (3 lines). That is 4 + 2 + 3 = 9 lines. The triangles are: ABC, BCD, CDA, DAB, AXB, BXC, CXD, DXA, and PQR 9 triangles with 9 lines. Could have done 13 triangles with 7 lines by drawing a line from A to BC.
