A parallelogram has one angle that measures 90°. What are the measures of the other three angles in the parallelogram?

Respuesta :

Answer:

All the others are 90 degrees too

Step-by-step explanation:

In a parallelogram opposite angles are congruent. Also in a quadrilateral the sum of angles is 360 degrees. since their are two pairs of congruent angles you could make an equation and it would look like this: 180+2x =360. x would be 90 making every angle 90 degrees
