Abcdefgh is a regular octagon. the minimum degree of rotation by which this octagon can map onto itself is (30 ; 45 ; 90 ; 120 °). it will take ( 2 ; 4 ; 6 ; 8 ) increments of that degree of clockwise rotation for a′ (the image of a) to coincide with c.

45°

2 - Clockwise

Step-by-step explanation:

ABCDEFGH is a regular octagon.

The minimum degree of rotation by which this octagon can map onto itself.

For rotation we have to find the central angle of each side.

Complete angle = 360°

A regular octagon has 8 equal sides. All sides make same angle at center.

8Ф = 360°

Ф = 45°

If we rotate regular octagon by 45° then it map onto itself.

Hence, 45° correct answer.  

After 2 times clockwise rotation by 45° each time. We will get the image of A coincide with C as shown in attach figure.

C is second vertex of A.

yes because they have the same amount of green and blur marbles.
