Properties of a Rhombus: • All properties of a parallelogram • All sides are congruent (equilateral) • The diagonals are perpendicular • The diagonals bisect the angles B A D C
Hypotenuse B A Since the diagonals of a rhombus are perpendicular, what kind of triangles are formed? Right triangles Leg Leg E Therefore we can use what theorem? Pythagorean Theorem D C Hypotenuse Legs
Page 12 4 Since the diagonals form a right angle, then they are perpendicular and is a rhombus
