Understanding Kites in Geometry

The video tutorial introduces the geometric shape known as a kite, discussing its properties such as congruent sides and angles, perpendicular diagonals, and how diagonals bisect angles. It provides several example problems, including calculating angles, area, perimeter, and solving algebraic expressions related to kites.

Which of the following is true about the diagonals of a kite?

• They are congruent to the sides.

• They bisect each other at right angles.

• They are equal in length.

• They are parallel.

If angle A in a kite is 60 degrees and angle C is 100 degrees, what is the measure of angle B?

• 80 degrees

• 90 degrees

• 100 degrees

• 120 degrees
