A 45 degree elbow will not make a right angle, but two will, if connected in line so that they continue the turn in the same direction. (45o + 45o = 90o, a right angle.)
Each exterior angle is 45 degrees (interior angle = 135 degrees).
Hint: 90/2=...
59 degree
a right ANGLE (not angel) is ninety degrees or straight up as seen from the horizontal, example, a street corner on a map, oriented properly. four right angle make up a square.
To make accurate 90 degree and angle cuts .

Each exterior angle is 45 degrees (interior angle = 135 degrees).
Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.

NO, because each intercecting line does not make a right angle-some could make acute or obtuse angles. To be perpendicular the lines that meet have to make a right angle(90 degree angle) or else they will not be perpendicular.
An isosceles triangle consists of a 90 degree angle and two 45 degree angles
that doesn't make sense. At least not to me...
