To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n – 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).
What is the diagonal of a triangle?
A diagonal of a polygon is a line from a vertex to a non-adjacent vertex. So a triangle, the simplest polygon, has no diagonals. You cannot draw a line from one interior angle to any other interior angle that is not also a side of the triangle. A quadrilateral, the next-simplest, has two diagonals.
What is the equation of a diagonal line?
In it y and x are the y-coordinate and x-coordinate for a point on the line, b is the y-intercept of the line, and m is the line’s slope. The slope is given by the equation m=y2−y1x2−x1 m = y 2 − y 1 x 2 − x 1 , where y2, y1, x2, and x1 are the coordinates of two points on the line: (x1, y1) and (x2, y2).
