∆abc is translated 2 units down and 1 unit to the left. then it is rotated 90° clockwise about the origin to form ∆a′b′c′.

the coordinates of vertex a′ of ∆a′b′c′ are (-2,0), or (2,1), or (-1,-2), or (-2,1)
the coordinates of vertex b′ of ∆a′b′c′ are (1,-1), or (1,0), or (5,0), or (2,-3)
the coordinates of vertex c′ of ∆a′b′c′ are (-1,-1), or (3,0), or (-1,0), or (0,-3)

The coordinates of image are A'(-2,1), B'(1,0) and C'(-1,0).

Step-by-step explanation:

From the figure it is clear that the coordinates of triangle are A(0,0), B(1,3) and C(1,1).

∆ABC is translated 2 units down and 1 unit to the left.

Then it is rotated 90° clockwise about the origin to form ∆A′B′C′.

Therefore the coordinates of image are A'(-2,1), B'(1,0) and C'(-1,0).

A'(-2,1), B'(1,0) and C'(-1,0).

Step-by-step explanation:

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
