WebHow many diagonals does a pentagon has? A 3 B 4 C 5 D 6 Solution The correct option is C 5 A diagonal is a line segment joining two vertices of a polygon, when those vertices are not on the same edge. From the figure, it is clear that a pentagon has 5 diagonals. Suggest Corrections 6 Similar questions Q. WebThe kite is divided into two congruent triangles by the longer diagonal. The longer diagonal bisects the pair of opposite angles. The area of kite = 12× d1× d2, where d1, d2 are lengths of diagonals. Perimeter of a kite with sides a and b is given by 2 [a+b]. The sum of the interior angles of a kite = 360°. WebA diagonal of a regular polygon is a straight line joining two vertices which are not adjacent.
