Can a parallelogram have four acute angles justify your answer.

  • geometry -

    Sum of measures of interior angles of a polygon of n sides = (n - 2)*180 deg.

    parallelogram = 4 sides
    so, n = 4
    (4 - 2)*180
    2*180 = 360 deg in a parallelogram

    can you answer this now?

  • geometry -

    the answer is yes

  • geometry -

    No, you cannot have 4 acute angles
    since "acute" means less than 90°

    4 x (something less than 90) < 360
