Given a triangle abc at a = ( - 1, 3 ) b = ( 1, - 1 ) c = ( 2, 2 ) and if the triangle is rotated 90 ° clockwise about the point ( 4, 1 ), find the new location of the point a'.

The coordinates of A' are (6,6).

Step-by-step explanation:

It is given that in triangle ABC, A = (-1, 3), B = (1, - 1) and C = (2, 2).

If a point is rotated 90 ° clockwise about the point ( a,b ), then

It is given that the triangle is rotated 90 ° clockwise about the point ( 4, 1 ). So, a=4 and b=1.

The coordinates of A are (-1,3), So, the coordinates of A' are

Therefore the coordinates of A' are (6,6).
