2. Ray
3. Line.

Hope it is helpful.

Answer 2

#Line segment: A line segment has two end points with a definite length.

#Ray: A ray has one end point and infinitely extends in one direction.

#Straight line: A straight line has neither starting nor end point and is of infinite length.

#Acute angle: The angle that is between 0° and 90° is an acute angle, ∠A in the figure below.

#Obtuse angle: The angle that is between 90° and 180° is an obtuse angle, ∠B as shown below

#Right angle: The angle that is 90° is a Right angle, ∠C as shown below.

#Straight angle: The angle that is 180° is a straight angle, ∠AOB in the figure below.

#Supplementary angles:If the sum of two angles is 180° then the angles are called supplementary angles.

#Complementary angles:If the sum of two angles is 90° then the two angles are called complementary angles.
