Show that the bisectors of two adjacent supplementary angles include a right angle

Prove that the bisectors of two adjacent supplementary angles include a right angle.

Define supplementary angles.

Three statements are given below: I. In a ||gm, the angle bisectors of two adjacent angles enclose a right angle. I. The angle bisectors of a ||gm form a rectangle. III. The triangle formed by joining the midpoints of the sides of an isosceles triangle is not necessarily an isosceles triangle. Which is true?

Prove that bisectors of any two adjacent angles of a rhombus from a right angled triangle with common arm of the angles.

In a parallelogram; the bisectors of any two consecutive angles intersect at right angle.

Two supplementary angles are in ratio 2:3. Find the angles
