To multiply fractions by a whole number, you just multiply the numerator (top number) by the whole. Once you find that, divide the numerator by the denominator (bottom number), and you get a decimal version of the answer. If you don't know how to convert decimals to fractions, you can look it up on wikiHow. Thanks!
Well all for sided figures are known as quadrilaterals and if a quadrilateral has 4 right angles, it would either be a square or rectangle. A square is a quadrilateral that has 4 right angles and 4 equal sides. A rectangle, however, is a quadrilateral that has 4 right angles with two sets of parallel lines! 2k Views Â· View Upvoters
No. A quadrilateral is simply a 4 sided polygon. There are 2 special subsets of polygons. The first is a trapezoid, which has 1 pair of opposite sides being parallel. If the other two pairs of base angles and opposite sides are congruent, then the trapezoid is isosceles. The four sides in a trapezoid are NEVER congruent. The other special subset of quadrilaterals is parallelograms. A parallelogram has opposite sides being both congruent and parallel. Opposite angles are also congruent and consecutive angles are supplementary (= 180). Subsets of parallelograms are rectangles, where all the angles are right angles (=90) and rhombuses, which DO have all 4 sides being congruent. A special quadrilateral that is BOTH a rhombus and a rectangle is the square. In short, only squares and rhombuses have 4 congruent sides. The rest do not.
