Given:
y(t1 + t2) = 2x + 2at1t2. y(t2 + t3) = 2x + 2at2t3 and, y(t3 + t1) = 2x + 2at1t3.
To find:
Point of intersection of pair of lines.
Concept Used:
Point of intersection of two lines.
Explanation:
2x − y (t1 + t2) + 2a t1t2 = 0 … (1)
2x − y (t2 + t3) + 2a t2t3 = 0 … (2)
2x − y (t3 + t1) + 2a t1t3 = 0 … (3)
Solving (1) and (2) using cross - multiplication method:
Solving (1) and (3) using cross - multiplication method:
Solving (2) and (3) using cross - multiplication method:
Hence, the coordinates of the vertices of the triangle are (at22,2at2),(at21,2at1) and (at23,2at3)
