Riangle abc was transformed using the rule (x, y) → (–y, x). the vertices of the triangles are shown. a (–1, 1) b (1, 1) c (1, 4) a' (–1, –1) b' (–1, 1) c' (–4, 1) which best describes the transformation? the transformation was a 90° rotation about the origin. the transformation was a 180° rotation about the origin. the transformation was a 270° rotation about the origin. the transformation was a 360° rotation about the origin.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
