5. Consider a triangle represented by A(0, 0), B(1, 1), C(5,2). The triangle is rotated by 45 degrees
about a point PC -1, -1

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

A®(-1, V2 -1). B'(-1. 2v2 – 1). C'((3/2)/2 – 1. (9/2)2 – 1)

A'(2-1,-1), B'( 212 – 1. -1). C'((3/2)2 – 1. (9/2)2 – 1)

A(-1. v2 -1), B'( 2v2 – 1.-1). C'(19/2)2 – 1. (3/2)2 – 1)

A'(-1, V2 -1), B'(2v2 – 1. -1). C'((3/2)V2 – 1. (9/2)2 – 1)​
