Let $A \equiv (3, 2)$ and $B \equiv (5, 1)$. $ABP$ is an equilateral triangle is constructed on the side of $AB$ remote from the origin then the orthocentre of triangle $ABP$ is
$\left( {4 - \frac{1}{2}\sqrt 3 ,\,\,\frac{3}{2} - \sqrt 3 } \right)$
$\left( {4 + \frac{1}{2}\sqrt 3 ,\,\,\frac{3}{2} + \sqrt 3 } \right)$
$\left( {4 - \frac{1}{6}\sqrt 3 ,\,\,\frac{3}{2} - \frac{1}{3}\sqrt 3 } \right)$
$\left( {4 + \frac{1}{6}\sqrt 3 ,\,\,\frac{3}{2} + \frac{1}{3}\sqrt 3 } \right)$
The area enclosed within the curve $|x| + |y| = 1$ is
The area of the triangle bounded by the straight line $ax + by + c = 0,\,\,\,\,(a,b,c \ne 0)$ and the coordinate axes is
The co-ordinates of three points $A(-4, 0) ; B(2, 1)$ and $C(3, 1)$ determine the vertices of an equilateral trapezium $ABCD$ . The co-ordinates of the vertex $D$ are :
Show that the path of a moving point such that its distances from two lines $3 x-2 y=5$ and $3 x+2 y=5$ are equal is a straight line.
If the straight line $ax + by + c = 0$ always passes through $(1, -2),$ then $a, b, c$ are
