Question

question 9 of 10 what degree of rotation about the origin will cause the triangle below to map onto itself? image of coordinate plane with triangle a. 270°

Explanation:

Answer:

(Assuming the triangle has rotational symmetry of 360° (or 0°), but likely a typo in option B (maybe 360°). If we consider standard rotational symmetry for a triangle (if it's a regular triangle, but here it's a right triangle? Wait, maybe the coordinates: Let's assume points. Wait, maybe the triangle is symmetric under 360° rotation (full rotation). But maybe the options have 360° (option B maybe a typo like 360°). So the answer is 360° (or if options have 360°, then that. But since the user's option B is cut, but likely the correct answer is 360° (or 0°), but in standard terms, 360° rotation maps any figure to itself. So the answer is 360° (assuming option B is 360°). So:

B. 360° (assuming the typo, as 270° won't map a non-symmetric triangle, but full rotation 360° does.)
