# What shape has diagonals that are perpendicular?

## What shape has diagonals that are perpendicular?

Rhombus diagonals
Sal proves that the diagonals of a rhombus are perpendicular, and that they intersect at the midpoints of both.

Does a kite have perpendicular diagonals?

Proof: The diagonals of a kite are perpendicular.

Does a rectangle has diagonals that are perpendicular?

If in case of square and rhombus, the diagonals are perpendicular to each other. But for rectangles, parallelograms, trapeziums the diagonals are not perpendicular. The diagonals of a rectangle are not perpendicular to each other. If we draw a square, their diagonals are always perpendicular.

### What are perpendicular diagonals?

The Diagonals of Squares are Perpendicular to Each Other The diagonals of squares are equal to each other, they bisect each other, and they are perpendicular to each other. Just like rectangles are a special type of parallelogram, squares are a special type of rectangles, in which all the sides are equal.

What shape is diagonals are perpendicular and congruent?

A quadrilateral that has diagonals that bisect and are perpendicular must be a square. A kite with congruent diagonals is a square.

How do you prove diagonals are perpendicular?

Proof that the diagonals of a rhombus are perpendicular Corresponding parts of congruent triangles are congruent, so all 4 angles (the ones in the middle) are congruent. This leads to the fact that they are all equal to 90 degrees, and the diagonals are perpendicular to each other.

#### Why diagonals of kite are perpendicular?

We have already shown that the diagonal that connects the two corners formed by the sides that are equal bisects the angles at those corners. So it is now easy to show another property of the diagonals of kites- they are perpendicular to each other.

Are diagonals of parallelogram perpendicular to each other?

The diagonals of a parallelogram bisect each other. diagonals may be perpendicular may be not. Special types of parallelogram with perpendicular diagonals are square and rhombus. So the correct answer is option C.

Are the diagonals of a parallelogram always perpendicular?

The diagonals of a parallelogram are sometimes congruent. The diagonals of a rhombus are always perpendicular. The consecutive angles of a parallelogram are never complementary.

## How do you know if diagonals are perpendicular?

To prove that two lines are perpendicular, when all we have are those two lines, we can use the Linear Pair Perpendicular Theorem – If two straight lines intersect at a point and form a linear pair of equal angles, they are perpendicular.

Are diagonals of parallelogram perpendicular bisector?

All of the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary). The diagonals bisect the angles. The diagonals are perpendicular bisectors of each other.

What shapes have congruent diagonals?

Rectangle always have congruent diagonals. Step-by-step explanation: Given some figures kite, quadrilateral, rectangle and rhombus. we have to find which of these always have congruent diagonals. The diagonals of a kite intersect at a right angle and have exactly one pair of opposite angles congruent.

### Which quadrilaterals must have perpendicular diagonals?

In general, any quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a kite. Every rhombus is a kite, and any quadrilateral that is both a kite and parallelogram is a rhombus.

What shape has perpendicular sides?

In a square or other rectangle, all pairs of adjacent sides are perpendicular. A right trapezoid is a trapezoid that has two pairs of adjacent sides that are perpendicular. Each of the four maltitudes of a quadrilateral is a perpendicular to a side through the midpoint of the opposite side.

Are diagonals perpendicular in parallelograms?

The diagonals are congruent. The diagonals are perpendicular to and bisect each other. A square is a special type of parallelogram whose all angles and sides are equal. Also, a parallelogram becomes a square when the diagonals are equal and right bisectors of each other.
