Rhombus and square are the only quadrilaterals whose diagonals bisect the angles of the quadrilateral. In both these quadrilaterals, the diagonals intersect at right angles, dividing each angle into two equal parts.

Any quadrilateral other than a square or kite could have diagonals meeting at 30 degrees.

The quadrilateral that must have diagonals that are congruent and perpendicular is the square. This is because its diagonals form a right angle at its center.

The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?

You would have to consider a triangle formed by one diagonal and two sides of the quadrilateral. If you know the lengths of these sides, and the measure of the angle between them, you can use the cosine law to find the diagonal. c2 = a2 + b2 -2ab(cosC)
