Question

susan will rotate triangle abc 180° about one of the labeled points. susan says, \the image will not touch the pre - image at all.\ which points could be her center of rotation? select each correct answer. point c point d point e point f

Explanation:

Step1: Recall rotation property

A 180 - degree rotation flips a figure across the center of rotation.

Step2: Analyze each point

If rotate about point C, image will touch at C. If about D, it will touch. If about E, image won't touch. If about a non - shown point F outside the triangle such that distance from all triangle points is sufficient, image won't touch.

Answer:

C. point E, F. point F (assuming F is an appropriate outside - the - triangle point)
