Respuesta :

A rectangle is a parallelogram which internal angles are all 90°

To find if the given parallelogram is a rectangle, we should:

• Find the slope of the segment AB

,

• Find the slope of the segment BC

,

• Multiply both results. If the product is -1, then AB and BC are perpendicular

,

• Find the slope of DC

,

• Find the slope of AD

,

• If the slope of DC is equal to the slope of AB, both segments are parallel

,

• If the slope of AD is equal to the slope of BC are equal, both segments are parallel

If all the conditions above are met, the parallelogram is a rectangle
