Question

7. Plot the following points and write the name of the
quadrilateral so formed in each case :
(iii) A(-2,-2), B(-4,2), C(-6, -2) and D(-4,-6)
​

Answer 1

Answer:

ok quad

ab = √(-4+2) ^2 + (2+2)^2 = √4 +16 =√20

bc =√(-6+4) ^2+ (-2-2) ^2 = √4+16 = √ 20

cd= √ (-4+6) ^2 + (-6+2) ^2 = √ 20

ad= √( -4+2) ^2 + ( -6+2) ^2 =√20

now just find daigonals if they match it's a square

if not then it's a rhombus
