Consider a triangle represented by A(0, 0), B(1, 1), C(5, 2). The triangle is rotated by 45 degrees about a point P( -1, -1). The co-ordinates of the new triangle obtained after rotation shall be

• A. A'(-1, √2 -1), B'(-1, 2√2 - 1), C'((3/2)√2 - 1, (9/2)√2 - 1)
• B. A'(√2 -1,- 1), B'( 2√2 - 1, -1), C'((3/2)√2 - 1, (9/2)√2 - 1)
• C. A'(-1, √2 -1), B'(2√2 - 1, -1), C'((3/2)√2 - 1, (9/2)√2 - 1)
• D. A'(-1, √2 -1), B'( 2√2 - 1, -1), C'((9/2)√2 - 1, (3/2)√2 - 1)
