Answer» Obviously, it is a trapezium. `a = sqrt(37)` `b = sqrt(37)` `therefore a =b` Hence, it is and isosceles trapezium. Therefore, it is a cyclic QUADRILATERAL. b. ac= bd `"or " (b)/(c) = (a)/(d)` `"tan "theta = (b)/(c)` `"tan "PHI = (a)/(d)` `"or " theta = phi` Hence, it is a cyclic quadrrilateral. c. `ax+- by +-c = 0` `"If " y=0, y=+-(c)/(a)` `"If " x= 0, y= +-(c)/(d)` Therefore, it is a rhombus. d. (x-6)(x-2) =0 x = 6 and x = 2 `y^(2) - 14y+45=0` (y-9)(y-5) = 0 Therefore, it is a SQUARE. |
