It is true that every trapezoid is a quadrilateral
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.
The measures for quadrilaterals ABCD and QRST are shown.Which statement is true?
only quadrilateral QRST is a kite

Show that if diagonals of a quadrilateral bisects each other then it is a rhombus?
This cannot be proven, because it is not generally true. If the diagonals of a quadrilateral bisect each other, then it is a parallelogram. And conversely, the diagonals of any parallelogram bisect each other. However not every parallelogram is a rhombus.However, if the diagonals are perpendicular bisectors, then we have a rhombus.Consider quadrilateral ABCD, with diagonals intersecting at X, whereAC and BD are perpendicular;AX=XC;BX=XD.Then angles AXB, BXC, CXD, DXA are all right angles and are congruent.By the ASA theorem, triangles AXB, BXC, CXD and DXA are all congruent.This means that AB=BC=CD=DA.Since the sides of the quadrilateral ABCD are congruent, it is a rhombus.
2 plus 3 equals 5 true or false?
True.
True or false pH equals -log H3O plus?

Is a square also a rhombus?
A square is not a rhombus it is a quadrilateral. A Rhombus is also a quadrilateral. Plus, I have extra information for you. Did you know that quadrilaterals have four sides? Well its true!
