What is the distance formula 

• D=√(x₂-x₁)²-(y₁-y₂)²

• D=√(x₂-x₁)²+(y₁-y₂)²

• D=√(x₂-x₁)+(y₁-y₂)

Name all the specific parallelograms that have each property (Diagonals are perpendicular) 

• Rectangle, Kite

• Square, Kite 

• Rhombus, Rectangle 

• Square, Rhombus 

Parallelogram wxyz has diagonals xz and wy and  xz= √(a-−b)² + (0-c)² = √(a+b)² + c²
and wy = √(c-0)² + (a+b)² = √(a+b)² + −c² so are the diagonals congruent?

• no, the diagonals are not congruent

• yes, the diagonals are congruent
