The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
Supplementary angles add up to 180 degrees
The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.The interior angles add up to (20-2)*180 = 18*180 = 3240 degrees.

The question probably refers to the internal angles of a triangle which total 180° . Also, the angle at the centre of a circle and subtended by half the circle is 180°.
The angles in a semi-circle add up to 180
The angles of a semi-circle are on a straight line and angles on a straight line add up to 180 degrees.
Two angles that add up to 180 degrees are called supplementary angles.
Supplementary angles add up to 180 degrees

No, the angles in a quadrilateral add up to 360 degrees. The angles in a triangle add up to 180 degrees.
If all of the angles add to 180 degrees the figure is a triangle. * * * * * That is if they form a plane figure. Angles that add to 1890 degrees are called supplementary angles.
