Instructions: select the correct answer from each drop-down menu. abcdefgh is a regular octagon. the minimum degree of rotation by which this octagon can map onto itself is °. it will take increments of that degree of clockwise rotation for a′ (the image of a) to coincide with c. nextreset

Remember that regular octagon is a figure with eight sides, where all of them are equal. The image attached shows a regular octagon.

So, if we want to map the octagon on to itself using rotation, we need to rotate 90° clockwise, or make to moves of 45° each, that way the octagon would be as the original one because it has equal sides.

When you rotate the first 45°, you would have like an inclined octagon, so you need to rotate another 45° to get the same octagon as the original.

So, the minimum degree would be 45°, doing it twice.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
