Answer 2

Answer:

→ Line Segment

A line segment is a part of a line that has two end points. It is denoted by two letters that are found in both the ends of the segment and will have a bar on top of it. To represent a line segment AB, we write it as:

$\sf{\overline{AB}}$

→ Acute angle

An angle that measures below 90° is known as an acute angle. It can have any measure between 0° and 90°, that is, angle measure of 1°-89°. Once an angle measures 90°, it becomes a right angle.

→ Right angle

An angle that measures sharp 90° is known as a right angle. It is a L-shaped angled and the angle is marked as a square unlike other angles where it is marked as a curved line.

→ Ray

A ray is a line segment that has only one end point. That is, it has a starts from a starting point and keeps on extending in a particular direction to infinity. Even though we can say that ray has only one point, it can páss through another point when extended endlessly. Two rays form an angle where the two rays have a common start point. A ray is denoted by by two letters that denote the starting point and another that is located in any other part of the ray with a right arrow on top of it. To denote a ray PR:

$\sf{\overrightarrow{PR}}$

→ Obtuse angle

An angle that measures more that 90° but less that 180° is known as an obtuse angle. It can have any measure between 90° and 180°, that is, it can have an angle measure of 91° to 179°. On reaching 180°, the angle becomes a straight angle.
