Question 1

You want to use a rotation matrix to rotate objects 60°. After rotation, what would the new vertex for point C (C') be on a triangle be if the original vertices were A(50,40), B(100,40) and C(75,200)?


◦

C'(210.9,-34.97)


◦

C'(135.9,165.03)


◦

C'(-135.9,165.03)


◦

C'(210.9,165.03)



Question 2

You want to rotate a triangle 120° around the z-axis. The triangle has vertices at A(100,0,-50), B(40,-30,0) and C(-20,100,50). What is the new point C' after rotation?


◦

C'(76.87,32.66,0)


◦

C'(76.87,32.66,50)


◦

C'(96.7,-32.66,50)


◦

C'(-76.7,-67.34,50)
