Answer explanation

A quadrilateral's interior angles add to 360. In a kite, one pair of angles are congruent. In this kite, <D is congruent to <F.

To solve:

add 95+ 115 = 210

subtract 360 - 210 = 150

divide 150 by 2 since angles D and F are the same size.

Find the value of y.

• 110

• 75

• None of these.

What is the Theorem of Kite?

• A quadrilateral with two pairs of adjacent congruent sides is a kite.

• A kite has two diagonals that are perpendicular to each other.

• A kite has two diagonals that bisect each other.

• A kite has two pairs of parallel sides.
