A quadrilateral can be inscribed in a circle if the opposite angles are supplementary. To determine which set of measures cannot form a cyclic quadrilateral, we calculate the sums of opposite angles for each set. The set of angles 100, 72, 80, and 108 has opposite angle pairs (100 + 80 = 180 and 72 + 108 = 180), which are supplementary. However, the other sets do not all yield supplementary pairs, with 42, 64, 118, and 136 failing this condition. Thus, 42, 64, 118, and 136 describe a quadrilateral that cannot be inscribed in a circle.
No, it cannot.
Yes providing that the face of the door has 4 sides
A quadrilateral cannot have just 3 lines of symmetry. If it has three, then it must have 4 and is a square.
It cannot exist. By definition, a quadrilateral only has 4 sides (from the word "quad" meaning 4)
If a figure has four sides, then it is a quadrilateral; it cannot be a triangle.
If it is a quadrilateral it cannot be "not a quadrilateral"!
None. A quadrilateral cannot be similar to any triangle.
No, it cannot.
A quadrilateral cannot have only three vertices.
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.

Yes it can because a quadrilateral is the general term given for any 4 sided shape.
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero sides.
A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero degrees.
