Parallelogram
- Parallelogram is a quadrilateral with two pair of parallel edges.
- Opposite angles equal, having more or less 90°.
- Edge \(\; a=c \;\) and \(\; b=d\)
- Angle \(\; x=z \;\) and \(\; y=w\)
- 2 diagonals
- 4 edges
- 4 vertexs
Edge formula
\(a = \frac {P}{2} - b \)
\(b = \frac {P}{2} - a \)
\(b = \frac {A}{h} \)
Where:
\(a\) = edge
\(b\) = edge
\(h\) = height
\(P\) = perimeter
\(A\) = area
Height formula
\(h = \frac {A}{b} \)
Where:
\(h\) = height
\(A\) = area
\(b\) = edge
Perimeter formula
\(P = 2 \left( a+b \right) \)
Where:
\(P\) = perimeter
\(a\) = edge
\(b\) = edge
Area formula
\(A=bh \)
Where:
\(A\) = area
\(b\) = edge
\(h\) = height
