The sum of the interior angles of any polygon can be found by applying the formula: 

 degrees, where  is the number of sides in the polygon. 

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. 

The missing angle can be found by finding the sum of the non-congruent opposite angles. Then divide the difference between  degrees and the non-congruent opposite angles sum by :   





This means that  is the sum of the remaining two angles, which must be opposite congruent angles. Therefore, the measurement for one of the angles is:

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. 

To find the sum of the remaining two angles, determine the difference between  degrees and the sum of the non-congruent opposite angles.

This means that  is the sum of the remaining two opposite angles.

A quadrilateral is considered a kite when one of the following is true:

(1) it has two disjoint pairs of sides are equal in length or

(2) one diagonal is the perpendicular bisector of the other diagonal. Given the information in the question, we know (2) is definitely true. 

To find  we must first find the values of all of the angles. 

The sum of angles within any quadrilateral is 360 degrees.

Therefore .

To find :

One of the rules governing kites is that the angles which lie between non-congruent sides are congruent to each other. Thus, we know one of the missing angles is also . Since all angles in a quadrilateral must sum to , we know that the other missing angle is

In order to solve this problem, first observe that the red diagonal line divides the kite into two triangles that each have side lengths of  and  Notice, the hypotenuse of the interior triangle is the red diagonal. Therefore, use the Pythagorean theorem: , where  the length of the red diagonal. 

The solution is: 

To solve this problem, apply the formula for finding the area of a kite: 



However, in this problem the question only provides information regarding the exact area. The lengths of the diagonals are represented as a ratio, where 


Therefore, it is necessary to plug the provided information into the area formula. Diagonal  is represented by  and diagonal .

The solution is:











Thus, if , then diagonal  must equal 

This problem can be solved by applying the area formula: 



Since this question provides the area of the kite and length of one diagonal, plug that information into the equation to solve for the missing diagonal. 

Thus the solution is: 

This problem can be solved by applying the area formula: 



Since this question provides the area of the kite and length of one diagonal, plug that information into the equation to solve for the missing diagonal. 

Thus the solution is:
