Coordinate of image triangle is M'(-6,-2),N'(-1,7) and P'(3,4)
Step-by-step explanation:
The given triangle MNP has coordinates of M(-2,6), N(7,1), and P(4,-3)
In matrix form, It can be written as :
Triangle has to rotate by angle of 90 degree at origin.
Counterclockwise Rotation matrix is given by :
For
Image of triangle MNP will be
=
=
Thus,
The coordinate of image triangle is M(-6,-2),N(-1,7) and P(3,4)
