Perpendicular lines make four 90 degree angles otherwise known as right angles.
There are: 2.5 times 90 = 225 degrees

Two right angles add up to 180 degrees because a right angle is 90 degrees
A square and a rectangle are two of them because they both have 4 interior right angles
None - the edge is curved so no straight sections to make angles
