Q1: A line segment has ________ endpoints.

Ans: two

Q2: An angle of exactly 90° is called a ________ angle.

Ans: right

Q3: A ray starts at one point and extends ________ in one direction.

Ans: infinitely

Q4: A protractor is used to ________ angles in degrees.

Ans: measure

Q5: An angle that is greater than 90° but less than 180° is called an ________ angle.

Ans: obtuse

True or False

Q1: A line segment has no endpoints.

Ans: False
Explanation: A line segment has two endpoints, so the statement is incorrect.

Q2: A straight angle is exactly 180°.

Ans: True
Explanation: By definition, a straight angle measures 180°.

Q3: An angle bisector divides an angle into three equal parts.

Ans: False
Explanation: An angle bisector divides an angle into two equal parts, not three.

Q4: A reflex angle is greater than 180° but less than 360°.

Ans: True
Explanation: A reflex angle measures more than 180° and less than 360°, so the statement is correct.

Q5: A ray has two endpoints.

Ans: False
Explanation: A ray has one endpoint and extends infinitely in one direction, so it does not have two endpoints.

Identify the Image

Q1: Identify which of the following is a ray.

Ans: C
Explanation: Figure C shows a point with an arrow at one end indicating it starts at one point and continues infinitely in one direction, so it is a ray.

Q2: Identify which of the following is a line segment.

Ans: B
Explanation: Figure B has two clear endpoints and does not extend beyond them, so it is a line segment.

Q3: Identify which of the following is a line.

Ans: A
Explanation: Figure A has arrows at both ends indicating it extends infinitely in both directions, so it is a line.
