3. Lesson 61:
*FYI...Formula for Area of a Parallelogram:
"Base" x "Height"
**the base & height must be perpendicular!
**Also....opposite angles are always congruent!!
B C
And...
Angle A = Angle C
Angle B = Angle D A D Angle A + Angle B = 180
Angle B + Angle C = 180
Angle C + Angle D = 180
Angle D + Angle A = 180
