NO!!! As the name Triangle ' suggest it is a shape of three angles, thereby three sides. A Quaderilateral is a shape of 4 sides. From Latin Tri = '3' Quad = '4'
yes, anything that has four sides is a quadrilateral.
Any shape that has not got 4 sides is a non-quadrilateral
Parallelogram
The formula for the area of a quadrilateral is... BASE*HEIGHT/3
a four sided figure with two 90degree angles on either end of the same line segment. (like a trapezoid)
TRUE!!!! Quadrilaterals can take the form of ;- Square Rectangle Rhombus Parallelogram Trapezium Kite Irregularly shaped quaderilateral .
Not all quaderilaterals satisfy this statement. Those quaderil;aterals that satisfy 'two pairs of parallel sides' are , a square, a rectangle, and a rhombus. Those quaderilaterals that do NOT satify ' two pairs of parallel sides' are, a trapezium, a kite, and an irregular shaped quaderilateral.
From Latin No. of sides ; Shape name. 3 ' Trigon (Triangle) 4 ' Tetragon (Quaderilateral) 5; Pentagon 6; Hexagon 7; Heptagon 8; Octagon 9; Nonagon 10l Decagon. NB Mathemtics uses are lot of names from the Classics, (Latin, and Classical Greek). That's were the above nomenclature comes from.
