No two sides of a triangle are ever parallel, and although
it isn't required, a triangle can have all acute angles.
That isn't possible for any shape with more than 3 sides.

What are all the properties of a rhombus?
all cogruent sides 2 acute angles 2 obtuse angles 2 sets of parallel lines the acute angles are 45 degrees the obtuse angles are135 degrees
What shape is quadrillateral?
A quadrilateral is a four-sided polygon (closed shape made with line segments). Quadrilaterals have four angles (vertices) and come in many different shapes, depending on the length of their sides and the kinds of angles they have. The five most common quadrilaterals are the rectangle, square, parallelogram, rhombus, and trapezoid. A rectangle is a quadrilateral with opposite sides congruent (same length) and parallel. It has four right (90º) angles. A square has ALL four sides that are congruent, and two pairs of parallel sides. It also has four right angles. A parallelogram has two pairs of parallel sides. They form two acute and two obtuse angles. A rhombus has two pairs of parallel sides, but all sides are congruent. They also form two acute and two obtuse angles. Finally, a trapezoid, has only one pair of parallel sides. The parallel sides are NOT congruent. A trapezoid can be formed by two acute and two obtuse angles, or by two right angles, one acute, and one obtuse angle.
What does not have 4 sides all sides are equal all angles are acute?
An equilateral triangle.
What quadrilateral has exactly 2 pairs of parallel sides no right angles and all sides are the same length?
A Rhombus had 2 pairs of parallel sides and has NO right angles. :)
Is every equilateral triangle acute explain?
Yes, because all angles are 60 degrees, and all sides are the same, therfore all angles are 60 degrees, which are acute angles.
What polygon has no parallel sides and all acute angles?
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
Has 4 sides and two acute angles and all opposite sides are parallel?
rhombus
What is a quadrilateral that has all opposite sides parallel and 2 acute and obtuse angles?
That would be a parallelogram.
What figure has 4 sides opposite sides parallel all sides equal 2 obtuse 2 acute angles?
parallelogram
What are all the properties of a rhombus?
all cogruent sides 2 acute angles 2 obtuse angles 2 sets of parallel lines the acute angles are 45 degrees the obtuse angles are135 degrees

You are a quadrangle have two pairs of parallel side of your angles are right angles you are not a square what are you?
parallelagram http://en.wikipedia.org/wiki/Parallelagram well specifically you would be a rectangle which has parallel sides like a square. a parallelogram can be a square or a rectangle because they all have parallel sides but only squares and rectangles have right angles on all sides. parallelograms have congruent sides which require acute and obtuse angles.
What is a quadrilateral with two sets of parallel sides and two angles acute and two others obtuse with all sides the same length?
rhombus
Which parallelogram has two pairs of parallel sides and no right angles?
A rhombus has two opposing acute angles (less than 90º) and two opposing obtuse (greater than 90º) angles, with the opposing sides being parallel and the sides being of equal length. A parallelogram can have the two acute angles and two obtuse angles, but have sides of different lengths. That is: two opposing sides shorter than the other two opposing sides. All angles total 360º
What has 2 pairs of parallel sides. They have 2 acute angles of the same size and 2 obtuse angles of the same size?
It is a parallelogram and if all 4 sides are equal then it is a rhombus
Does a acute triangle have 3 acute sides?
The word acute refers to angles, not sides. It does have all three angles are acute (less than 90°)
What has four sides and four angles Two angles are acute and two are acute?
If the figure has only four sides all together, then it's not possible for all four angles to be acute.
