you dont
No because a quadrilateral has 4 sides but doesn't have to have right angles. For example the. Trapezoid doesn't,t have right angles but it is a quadrilateral
they can be but dont have to be a square is a parallelogram but trapezoid is not
they dont
It's undefined, because we dont know the shape of the figure. If it's a square, the perimeter is 12.. if its a rectangle the perimeter MIGHT be 20... We cant determine if we dont know the figure.
circles dont have sides
Nope. Trapezoid, kite, etc. dont
they dont have two sets of parallel sides
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
A shape with three sides is called a triangle: 3 equal sides = equilateral 2 sides same length = isosceles 1 right angle = right-angled triangle
i dont know
no the answer would be 13 because of this a hexagon has 6 sides so 78 divided by 6 equals 13 inches khizar (dont get it?)

It is not possible to have 1 parallel side since it must be parallel to another side. A four sided shape with 1 PAIR of parallel sides is a trapezium (or trapezoid).
i dont know hehe haha
I dont know ;3
