Question

Find the new coordinates when you rotate 180 degrees around the origin,A(-1,2), B (2,3) and C (1,2)

Answer 1

A’ (1, -2)

B’ (-2, -3)

C’ (-1, -2)

Explanation:

When you rotate a point 180 degrees around the origin, each point of the given figure has to be changed from (x, y) to (-x, -y) 1. Let’s apply this rule to the given points:

Point A(-1, 2) will become A’ (1, -2).

Point B(2, 3) will become B’ (-2, -3).

Point C(1, 2) will become C’ (-1, -2).

Therefore, the new coordinates after rotating 180 degrees around the origin are:

A’ (1, -2)

B’ (-2, -3)

C’ (-1, -2)
