=Strait Angle- An Angle that measures exactly 180* Degrees.=<---------------o--------------->
450
because 180 degrees is a strait line, thefore unless the triangle does not have any strait lines the triangle has 3 180 degree angles in it.
50 degrees
It depends what angle, if it's a straight angle it is 180 degrees, but if it is a right angle then it's 90 degrees.
there is 90 degrees in a right angle derdder :):):):):):):):):):):):):)
A right angle is 90 degrees.
A right angle has 90 degrees.
A right angle has 90 degrees.
There are 90 degrees in a right angle.
