Asquare rotated about it's center by 360 degrees maps onto itself at what different angles of rotation. you can reflect a square onto itself across how many different lines of rotation

since a square has equal length sides

 it can be rotated 90, 180, 270 and 360 degrees

it's both, now can you answer my most recent question?

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
