Written by Jerry Ratzlaff on . Posted in Plane Geometry

• A two-dimensional figure that is a quadrilateral with two pairs of adjacent sides that are congruent.
• 2 diagonals
• a = b, c = d
• 4 sides
• 4 vertexs

### Area of a Kite formula

$$\large{ A_{area} =\frac { {d'} \; {D'} }{2} }$$

Where:

$$\large{ A_{area} }$$ = area

$$\large{ d' }$$ = diagonal

$$\large{ D' }$$ = diagonal

### Diagonal of a Kite formula

$$\large{ d' = 2\; \frac {A} {D'} }$$

$$\large{ D' = 2\; \frac {A} {d'} }$$

Where:

$$\large{ d' }$$ = diagonal

$$\large{ D' }$$ = diagonal

$$\large{ A_{area} }$$ = area

### Edge of a Kite formula

$$\large{ a = \frac {p} {2}\; - c }$$

$$\large{ c = \frac {p} {2} \;- a }$$

Where:

$$\large{ a, b, c, d }$$ = edge

$$\large{ p }$$ = perimeter

### Perimeter of a Kite formula

$$\large{ p= 2\; \left( a + c \right) }$$

$$\large{ p= 2\;a + 2\;c }$$

Where:

$$\large{ p }$$ = perimeter

$$\large{ a, b, c, d }$$ = edge
