Use matrices to determine the coordinates of the vertices of the rotated figure. rot 90 for trianglemnp with vertices m(-2,6), n(7,1), and p(4,-3)

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)
