Explore special parallelograms by following
these steps.
1. Move vertex A so that ZBAD is a
right angle. What do you notice
about the diagonals?
Sides
AB = 41 units
CD = 41 units
AD = 60 units
BC = 60 units
Diagonals
AC = 81 units
BD = 64 units
Angles
mZBAD = 76°
m ZAEB = 68°
Check

1) Move Vertex A So That Angle BAD Is A Right Angle. What You Notice About The Diagonals THE DIAGONAL LENGTHS ARE EQUAL

2) Mover Vertex A So That The Sides Are All Congruent. What Do You Noticed About The Diagonals THE DIAGONALS ARE PERPENDICULAR
