Are the diagonals of a rectangle always perpendicular?
As you can see from the pictures to the left, the diagonals of a rectangle do not intersect in a right angle (they are not perpendicular). (Unless the rectangle is a square.) And the angles formed by the intersection are not always the same measure (size).
Are the diagonals of a rectangle perpendicular bisector?
The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.
Is a rectangle perpendicular yes or no?
Like a square, a rectangle has lines that are perpendicular to two other lines. This means it also has four right angles.
What are diagonals in a rectangle?
Diagonals are the line segments that connect two non-adjacent vertices of polygons. Rectangles have two diagonals that connect two opposite vertices. They are the same size. In this activity, we will count the number of squares the diagonal passes through.
What do we know about the diagonals in a rectangle?
A rectangle has two diagonals. Each diagonal bisects the other. In other words, the point where the diagonals intersect (cross), divides each diagonal into two equal parts. Each diagonal divides the rectangle into two congruent right triangles.
Why does a rectangle sometimes have perpendicular diagonals?
A rectangle has perpendicular diagonals. The diagonals of a rhombus bisect each other. The diagonals of a parallelogram are perpendicular bisectors of each other. Two lines are perpendicular if and only if they form congruent adjacent angles.

How do you find the diagonal of a rectangle?
You can find the diagonal of a rectangle if you have the width and the height. The diagonal equals the square root of the width squared plus the height squared.
What parallelogram has perpendicular diagonals?
rhombus
If the diagonals of a parallelogram are perpendicular, it must be a rhombus. Diagonals of a parallelogram bisect the angles. A quadrilateral that has diagonals that bisect and are perpendicular must be a square.
Are diagonals perpendicular in a parallelogram?
If a quadrilateral is a rhombus, then it is a parallelogram. If a parallelogram is a rhombus, then its diagonals are perpendicular. If a parallelogram is a rhombus, then each diagonal bisects a pair of opposite angles. If the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus.
Are the two diagonals of a rectangle equal Why?
Yes, the diagonals of a rectangle are equal. This is because the two diagonals are the hypotenuse of the two right angled triangles formed by the diagonals. Since, the height and base of the two triangles are equal, by Pythagoras Theorem, the hypotenuse of the triangles are also equal.
How do you calculate the diagonal of a rectangle?
A rectangle has two diagonals, and each is the same length. If you know side lengths of the rectangle, you can easily find the length of the diagonal using the Pythagorean Theorem , since a diagonal divides a rectangle into two right triangles.
Which quadrilateral has congruent diagonals?
An Isosceles trapezoid is a quadrilateral that must have congruent diagonals. A square, because it is a rectangle, is a quadrilateral that must congruent diagonals.
What is quadrilateral with congruent diagonals?
A quadrilateral with congruent diagonals is a rectangle or a square. All four angles of a rectangle and a square are right angles, making the diagonals congruent. The diagonals of a rectangle and a square also bisect each other. Rectangles and squares are parallelograms with both pairs of opposite sides parallel and equal.
