Theorem:-5 (i) The degree measure of an arc or angle subtended by an arc at the centre is double the angle subtended by it at any point of alternate segment. (ii) Angle in the same segment of a circle are equal (iii) The angle in the semi circle is right angle. View Solution An...
A regular polygon is a shape whose sides are equal in length and interior angles are equal. All other polygons are considered irregular polygons. The square has four equal sides and four equal angles that are also right angles making it the only regular polygon. There are four right angles...

No. The sum of two adjacent angles on the same side of a segment is equal to 180 degrees. Two angles that add up to 180 degrees are called supplementary. Angles and Their Properties Angles are fundamental elements in the study of geometry. They are formed between two rays that share the...
An angle bisector is a line or ray that divides an angle in a triangle into two equal measures. The main properties of an angle bisector are that any point on the bisector of an angle is equidistant from the sides of the angle and the angle bisector divides the opposite side of a ...
According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side into two line segments that are proportional to the other two sides. Find how to prove the angle bisector theorem in an easy way at BYJU’S.
A straight angle is measured equal to 180 degrees. It is one of the six types of angles. Horizontal lines and vertical lines are straight lines. Properties and theorem along with examples at BYJU’S.
