A triangle is formed by the straight lines x + 2y - 3 = 0, 3x - 2y + 7 = 0 and y + 1 = 0. Find graphically :

(i) the co-ordinates of the vertices of the triangle.

(ii) the area of the triangle.

Find the distance between the points (2, -5) and (7, 7).

A is a point on x-axis, B = (5, -4) and AB = 5 units, find the co-ordinates of A.

Show that A(0, 0), B(5, 5) and C(-5, 5) are vertices of a right angled isosceles triangle.
