THEOREM: If a quadrilateral is an isosceles trapezoid, the diagonals are congruent. … THEOREM: If a quadrilateral is a kite, the diagonals are perpendicular. THEOREM: If a quadrilateral is a kite, it has one pair of opposite angles congruent.

## Are the diagonals of a kite equal?

The diagonals are perpendicular. (Thus the kites are exactly the quadrilaterals that are both tangential and orthodiagonal.) The two line segments connecting opposite points of tangency have equal length. One pair of opposite tangent lengths have equal length.

## Can a kite have congruent diagonals True or false?

In a kite, exactly 1 pair of opposite angles are congruent. … In a kite, diagonals bisect each other. False. A kite’s diagonals are congruent.

## What angles are congruent in a kite?

The angles between the congruent sides are called vertex angles. The other angles are called non-vertex angles. If we draw the diagonal through the vertex angles, we would have two congruent triangles. Theorem: The non-vertex angles of a kite are congruent.

## What are the 4 properties of a kite?

Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles and (3) perpendicular diagonals. Other important polygon properties to be familiar with include trapezoid properties, parallelogram properties, rhombus properties, and rectangle and square properties.

## What are the five properties of kite?

Properties:

- Opposite sides are parallel and equal in length.
- Opposite angles are equal in measure.
- Adjacent angles sum up to 180 degrees.
- It has 2 diagonals that bisect each other.
- Each diagonal divides the parallelogram into 2 congruent triangles.

## Are opposite sides of a kite congruent?

A kite is a quadrilateral in which two disjoint pairs of consecutive sides are congruent (“disjoint pairs” means that one side can’t be used in both pairs). … The opposite angles at the endpoints of the cross diagonal are congruent (angle J and angle L).

## What shapes have diagonals that are congruent?

## What shape does not always have congruent diagonals?

Every square is a rhombus. If the diagonals of a quadrilateral are perpendicular, then it is a rhombus. False – diagonals don’t have to be congruent or bisect each other. The diagonals of a rectangle bisect its angles.

## Do parallelograms have congruent diagonals?

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. A square is always a rhombus.

## What does congruent mean?

Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal.

## Do both diagonals of a kite bisect angles at the vertices?

its diagonals bisect each other at right angles, its diagonals bisect each vertex angle.

## How do you prove a kite?

How to Prove that a Quadrilateral Is a Kite

- If two disjoint pairs of consecutive sides of a quadrilateral are congruent, then it’s a kite (reverse of the kite definition).
- If one of the diagonals of a quadrilateral is the perpendicular bisector of the other, then it’s a kite (converse of a property).

## Can a kite have right angles?

Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.

## What does a kite equal up to?

By definition, a kite is a polygon with four total sides (quadrilateral). The sum of the interior angles of any quadrilateral must equal: degrees degrees degrees. Additionally, kites must have two sets of equivalent adjacent sides & one set of congruent opposite angles.

## How many degrees is a kite?
