## How do you show that ABCD is a parallelogram?

If — AB ≅ — CD and — BC ≅ — DA , then ABCD is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If ∠A ≅ ∠C and ∠B ≅ ∠D, then ABCD is a parallelogram.

## What makes something a kite?

In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other instead of being adjacent.

## What are the 5 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.

## Why is ABCD a parallelogram?

ABCD is a Parallelogram because one pair of opposite sides are parallel and congruent.

## What is the length of side ABA parallelogram ABCD?

ABCD is a parallelogram. The length of side AB is 8 unit.

## What does a kite equal?

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.

## Is a dart a kite?

A dart is a concave kite. That means two of its sides move inward, toward the inside of the shape, and one of the four interior angles is greater than 180° . A dart is also called a chevron or arrowhead.

## What is the area of the kite?

The final idea for Sal is that the area of a kite is given by A = 1/2 d1*d2 where d1 is one diagonal and d2 is the other. Kites also have diagonals that are perpendicular to each other.

## Can a kite have a right angle?

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.

## How many degrees is a kite?

360°
