A bisector splits the angle into to equal halves.
If AB is a perpendicular bisector of CD then four 90 degreee angles are formed.

|__ that is a right angle, if it was connected at least. But it's close enough! NONE! * * * * * It has one, which is the angle bisector.
One
None. All are right-angles (90 degrees). An acute angle is less than 90 degrees and more than zero degrees. The single angle formed by the letter V is an acute angle.
An acute angle has one angle.
There are infinitely many such angles.
A right angle only has one angle.
There are infinitely many angles which are acute.
When two perpendicular lines cross you get four equal angles of 90 degrees.
