### Chapter 7

Section 7.6 Properties of Kites/Arrow

Kite
• Kite a convex quadrilateral in which there are two pairs of congruent adjacent sides
Arrow
• a concave quadrilateral in which there are two pairs of congruent adjacent sides
Properties of a Kite

DIAGONALS

• are perpendicular
• One is the line of symmetry
• bisects 2 angles
• bisects the other diagonal
• What triangles are congruent

and why?

Properties of an Arrow
• DIAGONALS
• One is the line of symmetry
• - bisects angles
• Why are the triangles congruent?
• If the diagonals are
• extended they are
