Is the diagonals of a parellelogram perpendicular?
That is true for some parallelograms but not all. For example, the diagonals of a rhombus, kite or square are perpendicular, but those of a rectangle or general parallelogram are not.
Which type of quadilateral has diagonals which are not equal?
Parallelogram, trapezoid, rhombus and a kite are some of them Note that a square and a rectangle have diagonals of equal lengths
Does a parallelogram have diagonals that bisect each other?
They do in some parallelograms, not in others.
What are some thing that are perpendicular?
window pain
Do some parallelograms have equal diagonals true or false?
True when they are in the form of rectangles.
Is the diagonals of a parellelogram perpendicular?

Do rectangles have diagonals that are perpendicular?
I think rectangles do not have perpendicular sides. there are some perpendicular sides in a rectangle stupid person
Which figures have a right angle?
A right angle triangle, a square and a rectangle are some of them. Right angles are formed when perpendicular lines meet each other.
What shapes have diagonals bisect vertex angles?
Only a square and a rhombus will have all its diagonals bisecting vertices. In other shapes some - but not all - diagonals can bisect vertices.
Do parallelograms have congruent diagonals?
Some of them (rectangles) do.
What is the formula for diagonals?
You solve diagonals by finding the two perpendicular bases. You do the Pythagorean theorem to find them out.The diagonal of a rectangle can be found with the Pythagorean Theorem, sincethe diagonal is the hypotenuse of the right triangle formed by the sides of thefigure. It is the square root of the sum of the squares of the two sides.Finding the diagonal of a parallelogram would require some knowledge of trig.,e.g. the law of cosines, or something equivalent.
Which type of quadilateral has diagonals which are not equal?
Parallelogram, trapezoid, rhombus and a kite are some of them Note that a square and a rectangle have diagonals of equal lengths
What is true of all rhombuses?
-- The rhombus has four sides. -- All four of its sides are equal in length. -- Its opposite sides are parallel. -- The sum of its interior angles is 360 degrees. -- Its opposite angles are equal. -- Its diagonals are perpendicular and bisect each other. A rhombus with all 4 angles equal (at 90°) is called a square (which is a special kind of rectangle in which all 4 sides are of equal length); thus some rhombuses are rectangles (and some rectangles are rhombuses).
Why do shapes have perpendicular lines?
Some do, some don't.
Does a parallelogram have diagonals that bisect each other?
They do in some parallelograms, not in others.
What are some traits of a parallelogram?
It is a 4 sided quadrilateral It has 4 interior angles that add up to 360 degrees Its opposite angles are equal It has 2 pairs of opposite parallel sides It has 2 diagonals It will tessellate Its perimeter is the sum of its 4 sides Its area is base times perpendicular height
How many diagonal lines do a heptagon has?
A seven sided figure has 14 diagonals. Each vertices has 4 diagonals (but of course some are shared diagonals). The best thing to do is draw a regular heptagon, draw all the diagonals (lines connecting non-adjacent vertices) in pencil and then go back with a red or blue pen and count the diagonals as you trace each line in the different color.
