Inscribed Angles are angles that you can make it half or another same angle degree. EX:1 Making it half is very easy! Draw an angle, its normal how many degrees! Make a circle at the center of the angle, then you will draw points on the lines of angle from circles. Make the points A and B, then make radius from A and B once you draw it, then draw A from B. Then again from B to A, then you will make a point again when you round it. Then you just have to measure for EX its 90 degrees and you made it half it will be 45 degree that's it
