Answer:
Step-by-step explanation:
Given that there is a triangle XYZ with vertices (0, 0), Y(0, –2), and Z(–2, –2)
This triangle is rotated to form image triangle X'(0, 0), Y'(2, 0), and Z'(2, –2).
We find that origin remains the same.
Hence point of rotation is about the origin
Now (0,-2) is transformed to (2,0)
This is possible if point is rotated about origin anticlockwise a degree of 90
Let us check new coordinate of Z by anticlockwise rotation of 90
We get Z'(2,-2)
Hence the transformation is rotation about origin anticlockwise by degree 90
