Q: 1. What types of important questions are usually asked from Class 7 Maths Chapter 5 – Parallel and Intersecting Lines?

Chapter 5 often includes MCQs, very short, short, long, and diagram-based questions on parallel and intersecting lines. Important questions may test definitions, properties, and naming or drawing diagrams. Practice with worksheets and marking hints improves your score and familiarity with exam patterns.

Q: 2. How should I answer 2 or 3 mark questions on parallel and intersecting lines for full marks?

To score full in 2 or 3-mark questions, always include key definitions, correct diagrams, and stepwise explanations as per NCERT. Use command words like ‘state’, ‘explain’, or ‘draw’. Highlight each step for proper marking and avoid skipping definitions or diagrams when asked.

Q: 4. Are diagrams or labelled figures compulsory in important questions for Chapter 5?

Yes, diagrams or labelled figures are often required, especially for identification or explanation questions. Always draw clear diagrams, label all points, and match the question’s instructions. Well-labelled diagrams bring easy marks in CBSE exams on lines and angles topics.

Q: 5. Where can I find a parallel and intersecting lines Class 7 worksheet with answers PDF for practice?

Parallel and Intersecting Lines Class 7 Worksheet with Answers and Solutions

1. Multiple choice questions.

Q1. Which of the following statements is true about parallel lines?

(a) They never meet, however far extended
(b) They meet at one point
(c) They meet at two points
(d) They cross each other

Answer: (a) They never meet, however far extended

Q2. What is the measure of each angle formed when two lines are perpendicular?

(a) $60^\circ$
(b) $90^\circ$
(c) $120^\circ$
(d) $45^\circ$

Answer: (b) $90^\circ$

Q3. When a transversal crosses two parallel lines, how many unique angle measures are formed?

(a) 2
(b) 4
(c) 6
(d) 8

Answer: (b) 4

Q4. Vertically opposite angles formed by two intersecting lines are:

(a) Always unequal
(b) Sometimes equal
(c) Always equal
(d) Never form angles

Answer: (c) Always equal

2. Very Short Answer (VSA).

Q1. Define parallel lines.

Answer: Parallel lines are lines in the same plane that do not meet, no matter how far they are extended in both directions.

Q2. What are corresponding angles?

Answer: When a transversal cuts two lines, the angles at the same position in each intersection are called corresponding angles.

Q3. State the sum of linear pair of angles.

Answer: The sum of a linear pair of angles is always $180^\circ$.

Q4. What is a transversal?

Answer: A transversal is a line that intersects two or more lines at different points on the same plane.

3. Short Answer Questions.

Q1. In Fig. 5.2, if angle a = $120^\circ$, what are the measures of angles b, c and d? Explain your answer.

Answer: In Fig. 5.2, since $\angle a + \angle b = 180^\circ$, $\angle b = 180^\circ - 120^\circ = 60^\circ$. Similarly, $\angle c = 120^\circ$ (vertically opposite angles are equal), and $\angle d = 60^\circ$ (since linear pairs add to $180^\circ$).

Q2. Distinguish between parallel and intersecting lines with one example each from the classroom.

Answer: Parallel lines never meet (example: edges of the window pane), while intersecting lines meet at one point (example: two chalk lines drawn crossing on the board). Both are commonly seen in classroom objects.

Q3. How can you use a set square to draw lines parallel to a given line? Briefly describe the process.

Answer: Place the set square's right angle along the given line, and use a ruler along one side. Hold the ruler still, slide the set square to the desired location and draw the new line. This creates parallel lines as both form the same angle with the base.

Q4. If a transversal crosses two lines and forms equal corresponding angles, what can you say about these lines? Justify.

Answer: If a transversal forms equal corresponding angles with two lines, the lines must be parallel. This is because equal corresponding angles are a defining property of parallel lines.

4. True or False Questions.

Q1. All straight lines on a plane are parallel to each other.

Answer: False.

Q2. Two lines that intersect at right angles are called perpendicular lines.

Answer: True.

Q3. Linear pairs of angles always sum to $180^\circ$.

Answer: True.

Q4. Vertically opposite angles formed by two intersecting lines are not always equal.

Answer: False.

3. Fill in the Blanks Questions.

Q1. Two lines on a plane that never meet are called ________ lines.

Answer: parallel

Q2. When two lines intersect, the pairs of angles opposite to each other are called ________ angles.

Answer: vertically opposite

Q3. When a line intersects two lines at different points, it is called a ________.

Answer: transversal

Q4. If two lines intersect at right angles, they are called ________ lines.

Answer: perpendicular
