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.
An equilateral triangle.
Yes, because all angles are 60 degrees, and all sides are the same, therfore all angles are 60 degrees, which are acute angles.
A Rhombus had 2 pairs of parallel sides and has NO right angles. :)
A triangle having all angles less than 90 degrees is a polygon having no parallel sides and all acute angles.
rhombus
That would be a parallelogram.

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.
rhombus
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
It is a parallelogram and if all 4 sides are equal then it is a rhombus
The word acute refers to angles, not sides. It does have all three angles are acute (less than 90°)
If the figure has only four sides all together, then it's not possible for all four angles to be acute.
