The equation , y = 1 are the sides
an equilateral triangle
a right angled triangle
a isosceles triangle
an obtuse angled triangle
The equations of the lines through (1, 1) and making angles of 45° with the line x + y = 0 are
x - 1 = 0, x - y = 0
x - y = 0, y - 1 = 0
x + y - 2 = 0, y - 1 = 0
x - 1 = 0, y - 1 = 0
