What is a quadrilateral with equal diagonals which bisect each other?
A parallelogram with one right angle is a rectangle. A quadrilateral whose diagonals are equal and bisect each other is a rectangle.
How do you know if diagonals bisect each other?
In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. That is, each diagonal cuts the other into two equal parts.
Do the diagonals of a quadrilateral always bisect each other?
If a quadrilateral is a parallelogram, then its diagonals bisect each other.
Is the diagonal of a quadrilateral are equal?
The diagonals of a quadrilateral are equal and bisect each other.
How do you prove that the diagonals of a rectangle bisect each other?
1 Answer
- AC and OB are diagonals. In the figure let the intersecting point of OB and AC be P. To show that diagonals bisect each other we have to prove that OP = PB.
- OP = OB. Similarly we can prove that PC = PA. Thus diagonals bisect each other in a rectangle .
- ∴ The diagonals of a rectangle bisects each other and equal .
How do you prove the diagonals of a quadrilateral bisect each other?
Theorem: The diagonals of a parallelogram bisect each other. Proof: Given ABCD, let the diagonals AC and BD intersect at E, we must prove that AE ∼ = CE and BE ∼ = DE. The converse is also true: If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
How do you prove that the diagonals of a quadrilateral are equal?
Show that if the diagonals of a quadrilateral are equal and bisect each other at right angles, then it is a square.
- Given. Let ABCD be a quadrilateral and its diagonals AC and BD bisect each other at right angle at O.
- To prove. The Quadrilateral ABCD is a square.
- Solution. From ΔAOB and ΔCOD,
How do you prove that the diagonals of a square are equal?
To prove: Diagonals of a square are equal and bisect each other at right angles. Let ABCD be a square. Let the diagonals AC and BD intersect each other at a point O. Hence, the diagonals of a square are equal in length.
How do you prove that the diagonals of a rhombus bisect each other?
Let ABCD be a quadrilateral, whose diagonals AC and BD bisect each other at the right angle. So, we have, OA = OC, OB = OD, and ∠AOB = ∠BOC = ∠COD = ∠AOD = 90°. To prove ABCD a rhombus, we have to prove ABCD is a parallelogram and all the sides of ABCD are equal.
How to prove a quadrilateral is a square?
Show that if the diagonals of the quadrilateral are equal and bisect each other at right angles, then it is a square. > Show that if the diagonals Show that if the diagonals of the quadrilateral are equal and bisect each other at right angles, then it is a square.
How do you identify a quadrilateral with diagonals that bisect each other?
You are given a quadrilateral with diagonals that are identified as bisecting each other. [insert drawing of quadrilateral FISH with diagonals HI and FS, but make quadrilateral clearly NOT a parallelogram; show congruency marks on the two diagonals showing they are bisected]
What does it mean when diagonal bisects each other at 90 degrees?
When diagonal bisects eachother at 90 degree means all the four triangles are congruent. Opposite sides are equal. Since alternative angles are also equal these sides are also parellel. Angles of these triangles are 45 degree each besides one of 90 degrees.
How to prove that a quadrilateral is a rhombus?
Ex .8.1,3 (Method 1) Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. Given: Let ABCD be a quadrilateral, where diagonals bisect each other OA = OC, and OB = OD, And they bisect at right angles So, AOB = BOC = COD = AO (टीचू)
