NOImproved Answer:-Yes a rhombus has equal opposite acute angles and equal opposite obtuse angles
No, a rectangle's diagonals do not bisect opposite angles.
opposite angles of all parallelograms are always equal.
vertical angles Congruent
A square or a rectangle has opposite angles that add up to 180 degrees
Any pair of adjacent angles.
360. Any quadrilateral's angles add up to 360.
it is a square
Some paralleograms are rectangles. A right paralleogram is a rectangle. In the case of a rectangle, all angles formed by the sides are right angles and opposite sides are parallel. The sum of adjacent angles in a parallelogram is 180 degrees.
I have never come across the phrase "parallel angles". Please elaborate.
A paralleogram has no meaning. However, a parallelogram is a four sided plane (2-dimensional) figure which has two pairs of [opposite] sides that are parallel.
They are both quadrilaterals and they both have interior and exterior angles of 360 degrees.
No, a paralleogram that has even one right angle must have all right angles in order to keep the opposite sides parallel. So, a parallelogram will have either no right angles (in which case it will always have 2 acute angles and two obtuse angles) or it will have 4 right angles (in which case it will be called a square or a rectangle, and will obviously have no acute or obtuse angles).
No it cannot, because the interior angles of a parallelogram ... or of anyfour-sided figure for that matter ... must add up to 360 degrees.
Opposite angles are the angles opposite each other on an x but vertical angles are the angles that are opposite and congruent.
