In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints.
A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. We indicate the position of a point by placing a dot with a pencil.
an angle of 90°, as in a corner of a square, or formed by dividing a circle into quarters.
Obtuse Angle. more ... An obtuse angle is more than 90° but less than 180° In other words, it is between a right angle and a straight angle.
an angle of 180°.
An acute angle ("acute" meaning "sharp") is an angle smaller than a right angle (it is less than 90 degrees).
Angles larger than a right angle and smaller than a straight angle (between 90° and 180°) are called obtuse angles ("obtuse" meaning "blunt"). ... An angle equal to 1 turn (360° or 2π radians) is called a full angle, complete angle, or a perigon.
