What else can I help you with?
Can a parallelogram have 4 acute angles?
No, because it is a quadrilateral and all the angles have to add up to 360 degrees and the less possible degree and angle could have would be 90 so, parallelograms can only have 2 acute and 2 obtuse angles.
What has 2 acute angles and 2 obtuse angles?
parallelogram
Does a trapezoid have 90 degree right angle?
Not normally but it can have 2 right angles
What shape has 2 acute angles and 2 obtuse angles?
parallelogram
Is it possible to have a right isosceles triangle?
Yes, because 90+90=180, so if you have a 90 degree angle then divide 90 by 2 that is 45. So you would have one 90 degree angle, and two 45 degree angles.
What is the difference between a parallelogram and a rectangle?
A parallelogram has 2 equal obtuse angles and 2 equal acute angles whereas a rectangle has 4 equal 90 degree angles
What figure has 2 pairs of pararallel lines and no 90 degree angles?
A non-rectangular parallelogram.
Why is a rectangle a parallelogram but a parallelogram is not a rectangle?
A rectangle has three rules: -2 pairs of parallel sides -four 90 degree angles -2 pairs of congruent sides A parallelogram has three rules: -2 pairs of parallel sides - 2 pairs of congruent angles -2 pairs of congruent sides The only difference is that a rectangle has 90 degree angles, which a parallelogram doesn't have. That's why a parallelogram can't be a rectangle. A rectangle follows all the rules of being a parallelogram, so it can be a parallelogram.
Which quadrilaterals have opposite angles congruent?
A square and a rectangle have opposite equal 90 degree angles. A parallelogram and a rhombus have 2 opposite equal acute angles and 2 opposite equal obtuse angles.
Can a parallelogram have 2 45 degree angles and 2 75 degree 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.
How are a rectangle and a parallelogram different?
The main difference is that a rectangle has 4 equal interior right angles whereas a parallelogram has 2 equal interior obtuse angles and 2 equal interior acute anglesBoth have two sets of parallel lines, but a rectangle forms four equal 90 degree angles. A parallelogram does not have four equal angles.
How does a rectangle differ from a parallelogram?
A rectangle has 4 equal interior angles of 90 degrees whereas a parallelogram has 2 equal acute angles and 2 equal obtuse angles.
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
Can a parallelogram have 4 acute angles?
No, because it is a quadrilateral and all the angles have to add up to 360 degrees and the less possible degree and angle could have would be 90 so, parallelograms can only have 2 acute and 2 obtuse angles.
What supplementary angles have equal degree measure?
2 90 degree (right) angles
Does a parelleogram have any symmetrical sides?
Yes, a parallelogram has 2 pairs of symmetrical sides. A rectangle is an example of a parallelogram but with all of its angles being 90 degrees whereas in a typical parallelogram none of the angles are 90 degrees. Opposite sides will be of equal lengths.
Does a quadrangle have 90 degree angels?
No, but it can have 1, 2 or 4 ninety degree angles.
