Assertion : The diagonals of parallelogram formed by the lines
ax + by + c = 0, a´x + b´y + c = 0,
ax + by + c´ = 0, a´x + b´y + c´ = 0
will be perpendicular if aa´ + bb´ = 0
Reason : The diagonals of rhombus are always perpendicular.
ax + by + c = 0, a´x + b´y + c = 0,
ax + by + c´ = 0, a´x + b´y + c´ = 0
will be perpendicular if aa´ + bb´ = 0
Reason : The diagonals of rhombus are always perpendicular.
