A square has four equal sides and four equal angles.
18
well, 1 right angle is equal to 90 degrees, when added up, its 180.
In an isosceles triangle, the two angles at the bottom are equal. Subtract the sum of the two bottom angles from 180 to find how many degrees are in the top angle.
3. trisect means three
Three ! The answer is in the question !

how many lines of symmetry does a regular polygon with 32 sides have
I don't think you can. You can construct a 60º angle by compasses, but 65º sounds like a "Trisect" problem which (despite many claims to the contrary over many years) is not mathematically possible.

Two side are equal
A bisector splits the angle into to equal halves.

One degree of angle is equal to 3,600 seconds of angle.
A square has four equal sides and four equal angles.
