Quadrilateral abcd is a parallelogram is side ab equal to side CD?
always
In algebra how do you simplify ab x CD?
abcd
What is the perimeter of parallelogram abcd with ad equals 10 units ab equals 8 units ac equals 12 units ed equals 4.5 units?
If abcd is a parallelogram, then the lengths ab and ad are sufficient. The perimeter is 36 units.
In parallelogram ABCD AB equals 12 BC equals 16 plus 2x what is x?
Anything you like (as long as it is > -16 so that BC > 0). In a parallelogram, adjacent sides do not impose any restrictions on one another.
What is the answer for algebra abc plus ab?
You want: abc + ab Factor out the common terms which are "a" and "b" ab ( c + 1 )

A quadrilateral is a parallelogram if a pair of opposite sides is equal and parallel prove?
A quadrilateral is a parallelogram if one pair of opposite sides are equal and parallel Let ABCD be a quadrilateral in which ABCD and AB=CD, where means parallel to. Construct line AC and create triangles ABC and ADC. Now, in triangles ABC and ADC, AB=CD (given) AC = AC (common side) Angle BAC=Angle ACD (corresponding parts of corresponding triangles or CPCTC) Triangle ABC is congruent to triangle CDA by Side Angle Side Angle BCA =Angle DAC by CPCTC And since these are alternate angles, ADBC. Thus in the quadrilateral ABCD, ABCD and ADBC. We conclude ABCD is a parallelogram. var content_characters_counter = '1032';
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.
If one pair of sides of a quadrilateral is parallel and congruent then the quadrilateral is a parallelogram?
== == yes. suppose the quad ABCD has AB and CD equal and parallel. Then the triangles ABC and CDA are congruent by SAS axiom; so the quad is a parallelogram
Given ABCD what is the length of AB?
12
What is the perimeter if ABCD if ab is 12 centimeters and 11 centimeters?
This question cannot be answered because:ab cannot be 12 cm as well as 11 cm. The question says it is both!It may be assumed that ABCD is a quadrilateral, but there is no further information. Is it a parallelogram or another type of quadrilateral. If the latter, then the length of all four sides, or some of the angles is required.
In algebra how do you simplify ab x CD?
abcd
What is the perimeter of parallelogram ABCD?
Assuming ABCD marks the four corners, the perimeter = sum of the four sides = (AB + BC + CD + DA) where AB == the side from A to B etc.
What are the lengths of the diagonals of the quadrilateral abcd when ab is 4.3 cm bc is 3.4 cm cd is 3.8 cm angle abc is 95 degrees and angle bcd is 115 degrees?
If you mean quadrilateral ABCD then by using the cosine rule diagonal AC equals 5.71 cm and diagonal BD equals 6.08 cm both rounded to two decimal places.
If parallelogram ABCD is a square then AB will equal AC?
never
