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.

The minimum degree of rotation is by wich this octagon can map onto itself is 45° . It will take 2° increments of that degree of clockwise rotation for A´ to coincide with C

Step-by-step explanation:

I hope this is the octagon you are refering

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
