WebThe formula for the number of diagonals in a polygon with n sides is: n (n-3)/2 where n is the number of sides of the polygon. In the case of a triangle, we have n = 3, so we can substitute this value into the formula and get: 3 (3-3)/2 = 0 Explanation A diagonal is a line segment that connects any two non-consecutive vertices of a polygon. WebA regular hexagon has nine diagonals: the six shorter ones are equal to each other in length; the three longer ones are equal to each other in length and intersect each other at the center of the hexagon. The ratio of a long …

So as we see from Figure 2.5.3, sinA = 3 / 5. Thus, 2R = a sinA = 3 3 5 = 5 ⇒ R = 2.5 . Note that since R = 2.5, the diameter of the circle is 5, which is the same as AB. Thus, ¯ AB must be a diameter of the circle, and so the center O of the circle is the midpoint of ¯ AB. sharp error code f2-78
