Describe the symmetry of the figure. identify lines of symmetry, if any. find the angle and the order of any rotational symmetry.

What rotation was applied to triangle def to create d’e’f’?

What is the sum of the geometric series in which a1 = 7, r = 3, and an = 1,701? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio
