5) Show that the points (-3,2), (-5, -5), (2, -3) and (4,4) are the vertices of a rhombus.16 |
|
Answer» Step-by-step explanation: let these POINTS, A(-3,2),B(-5,-5),C(2,-3), and D(4,4) sides are, AB = √{(-5+3)²+(-5-2)²} = √{4+49} = √53 BC = √{(2+5)²+(-3+5)²} = √{49+4} = √53 CD = √{(4-2)²+(4+3)²} = √{4+49} = √53 AD = √{(4+3)²+(4-2)²} = √{49+4} = √53 and diagonals are, AC = √{(2+3)²+(-3-2)²} = √{25+25} = √50 BD = √{(4+5)²+(4+5)²} = √{81+81} = √162 So,it is a RHOMBUS because the sides are equal and diagonals are UNEQUAL which is the property of rhombus. |
