The length of diagonal AC in kite ABCD is 16.1 cm
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.
A kite is a quadrilateral (4 sides and angles) with two pair of equal consecutive sides.
From the diagram:
DE = 8cm / 2 = 4 cm
Using Pythagoras theorem:
AD² = AE² + DE²
9² = AE² + 4²
AE = 8.06 cm
AC= AE * 2 = 16.1 cm
