55 degrees.
to construct an angle of 20 degrees all you have to do is to trisect an angle of 60degrees
A reflex angle is an angle greater than 180 degrees and less than 360 degrees. To construct one draw two lines at an angle and draw the angle measurement circle around the side you normally don't do it on.
draw 2 angles that add up to 180 degrees
obtuse* angles are between 180 degrees and 90 degrees. Straight line and right angle.
It is the supplementary angle of 125 degrees which is 55 degrees
Any angle between 90 and 180 degrees - including 125 degrees - is an obtuse angle.
draw the outside angle if you want to show 270 degrees then you draw a 90 degree angle but draw the circle outside of it
55 degrees.
125/180
An obtuse angle of 135 degrees.
-235
an Obtuse angle
It is: 180-125 = 55 degrees
For all triangles drawn on a plain ( 2-dimensional) surfacem the sum of the three interior angles is 180 degrees. Hence if the sum of two angles is 125 degrees. Then the third angle is 180 - 125 = 55 degrees.
An obtuse angle.
A right angle measures 90 degrees
