There are 90o in a right angle. A right angle is one-quarter of a full circle i.e. 360o.
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
The definition of a right angle is one quarter of a circle. If you're using the popular system of 360 degrees in a circle, then a right angle is 90 degrees.

right-angle triangle has at least one right angle .
Yes. It follows from one of the circle theorems which states that the angle subtended in a semicircle is a right angle.
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
how do you draw a quadrangle that has at least 1 right angle.
The definition of a right angle is one quarter of a circle. If you're using the popular system of 360 degrees in a circle, then a right angle is 90 degrees.

90. A complete circle has 360 degrees; a right angle is one-quarter of this.
