perpendicular
They are two edges that make a 90 degree angle. However, the term is also loosely used for edges that make a 90 degree angle with the horizontal.
All you have to do to make a right angle out of a piece of string is put the string in the shape of an L. This will make a right angle
you cannot make a regular shape which has 3 right angles only, you will always end up with 4 right angles
You can make a four sided shape with 3 right angles, but it must have another right angle, too. So technically, yes.
that is impossible!!! you cant have 2 edges make a shape
No... a quadrilateral is a figure of 4 sides. Trapzoid, square, diamond.... get the picture? A right angle is an angle. It is formed by two lines intersecting. They don't even necessarily make a shape.
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
Ye. It's called a square.
I'm sorry there is no possible way to make a parallel lines form a right angle in any sort of shape unless u where to bend one of the lines in which case they would no longer be parallel.
90 degrees make a right angle. A corner of a piece of paper is an example. :)

Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.
