You can prove it if you can prove that one pair of opposite sides is parallel (and, strictly speaking, that the other pair is not).
Proving that the lines are parallel depends on the information available. Thier equations may have the same slope (gradient), or that the angles at their ends are supplementary, etc.
What else can I help you with?
What is quadrilateral with 1 pair of parallel sides?
Its a trapezium.
What polygon has one set of parallel lines?
A trapezoid or, in Britain, a trapezium. Other than in Britain, a trapezium is a quadrilateral with no parallel sides at all.
What quadrilateral has no rotational symmetry?
A trapezium, a kite, an arrowhead, a quadrilateral with 4 different sides. In fact, anything other than a parallelogram (and its special cases).
How do you prove that In a quadrilateral ABCD prove that AB plus BC plus CD plus DA 2( AC plus BD )?
You cannot prove it since it is not true for a general quadrilateral.
Can a quadrilateral have each of 4 angles a different measure?
Yes, be it a common convex quadrilateral or a concave quadrilateral. For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length. It is similar for a concave quadrilateral.
Is a trapezium a quadrilateral?
Yes a trapezium is a 4 sided quadrilateral
How do you prove a quadrilateral is a trapezium by similarity?
To prove a quadrilateral is a trapezium using similarity, you need to show that one pair of opposite sides is parallel. You can do this by demonstrating that the triangles formed by the non-parallel sides and the segments connecting the endpoints of the parallel sides are similar. If the angles formed by these triangles are equal (due to parallel lines creating corresponding angles), then the sides will be proportional, confirming the similarity. Thus, if you establish similarity in this way, you can conclude that the quadrilateral is a trapezium.
When is a trapezoid quadrilateral?
A trapezium is always a quadrilateral.
What makes a quadrilateral a trapezium?
Because a trapezium has 4 sides
What is the trapezium?
type 'shape of a trapezium' in Google then you get the shape of trapezium , quadrilateral , rhombus , ect...

What polygon does not have right angles but is a quadrangle?
Quadrangle isn't a polygon. Quadrilaterals are polygons. One's with possibilities of no right angles include: Kite Parallelogram Rhombus Complex Quadrilateral Simple Quadrilateral Concave Quadrilateral Convex Quadrilateral Tangential Quadrilateral Cyclic Quadrilateral Bicentric Quadrilateral Trapezium Isosceles Trapezium 3-Sided-Equal Trapezium
How any edges does a trapezium have?
A trapezium is a 4 sided quadrilateral shape
What quadrilateral has no parallel side?
A Trapezium is a quadrilateral with no parallel sides.
A trapezium can also be called a what?
A quadrilateral
Is a trapezium always a quadrilateral?
Yes.
Is a right-angled trapezium a quadrilateral?
Anything that has four sides is a quadrilateral.
