Triangle A is rotated 180° counterclockwise about the origin. Which figure is the transformed figure? plz help ill mark u as brainlies

Answer:BStep-by-step explanation:When you rotate a figure 180° counterclockwise or clockwise, you get the same result, the effect you get on each point you rotate is(x′, y′) = (-x, -y)You can look at the triangle as 3 points, A(1, -3), B(3, -1) and C(3, -5)So the new points using the previous formula would beA′ = (-1, 3)B′ = (-3, 1)C′ = (-3, 5)so the answer is option B
