Front

What is a kite in geometry?

Back

A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal in length.

Front

What are the properties of angles in a kite?

Back

In a kite, the angles between the unequal sides are equal, and the angles between the equal sides are also equal.

Front

How do you calculate the measure of an angle in a kite when given other angles?

Back

You can use the fact that the sum of the interior angles of a quadrilateral is 360 degrees to find the unknown angle.

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360 degrees.

Front

If angle WXY measures 133 degrees and angle ZYX measures 34 degrees, how do you find angle ZWY?

Back

You can find angle ZWY by using the equation: angle WXY + angle ZYX + angle ZWY + angle WYZ = 360 degrees.

What is the relationship between the angles in a kite?

Back

The angles opposite the equal sides are equal, and the angles adjacent to the unequal sides are supplementary.

Front

What is the measure of angle WYZ if angle WXY is 133 degrees and angle ZYX is 34 degrees?

Back

Angle WYZ can be found using the equation: angle WYZ = 360 - (angle WXY + angle ZYX + angle ZWY).
