Practice with A Tale of Three Intersecting Lines Class 7 Worksheet With Answers for Exams

1. Multiple choice questions.

Q1. Which of the following is a property of an equilateral triangle?

(a) All sides have different lengths
(b) All sides are equal and all angles are equal
(c) Only two sides are equal
(d) All angles are right angles

Answer: (b) All sides are equal and all angles are equal.

Q2. Which condition determines if three lengths can form a triangle?

(a) Sum of two lengths equals third
(b) Sum of smallest two lengths is greater than the largest
(c) Any three lengths always make a triangle
(d) All lengths must be equal

Answer: (b) Sum of smallest two lengths is greater than the largest.

Q3. The sum of all angles in any triangle is:

(a) $90^\circ$
(b) $360^\circ$
(c) $180^\circ$
(d) $120^\circ$

Answer: (c) $180^\circ$.

Q4. In a triangle, the altitude is:

(a) The longest side
(b) A line joining any two vertices
(c) The perpendicular from a vertex to the opposite side
(d) A bisector of any angle

Answer: (c) The perpendicular from a vertex to the opposite side.

2. Very Short Answer (VSA).

Q1. Define the triangle inequality.

Answer: Triangle inequality means the sum of the lengths of any two sides of a triangle is always greater than the third side.

Q2. What is an isosceles triangle?

Answer: A triangle with exactly two equal sides is called an isosceles triangle.

Q3. What is the sum of all the interior angles of a triangle?

Answer: The sum of the three interior angles of any triangle is always $180^\circ$.

Q4. State what is meant by the altitude of a triangle.

Answer: The altitude of a triangle is a perpendicular line segment drawn from a vertex to its opposite side.

3. Short Answer Questions.

Q1. Explain how to check whether lengths 3 cm, 4 cm, and 8 cm can form a triangle.

Answer: Check if the sum of any two sides is greater than the third. $3 + 4 = 7 < 8$, so 3 cm, 4 cm, and 8 cm cannot form a triangle because they do not satisfy the triangle inequality.

Q2. Describe the steps to construct a triangle when its three sides are known.

Answer:

Draw the base equal to one side.
With a compass, draw arcs from each endpoint with radii equal to the other two sides.
Mark intersection; join to endpoints to form the triangle.

Q3. How does the angle sum property help in determining the third angle of a triangle if two angles are known?

Answer: The angle sum property states the sum of all angles is $180^\circ$. If two angles are known, subtract their sum from $180^\circ$ to find the third: Third angle = $180^\circ$ − (sum of the other two angles).

Q4. Give the classification of triangles based on their angles and sides.

Answer: By sides: equilateral (all equal sides), isosceles (two equal sides), scalene (no equal sides). By angles: acute-angled (all angles less than $90^\circ$), right-angled (one $90^\circ$), obtuse-angled (one angle over $90^\circ$).

4. True or False Questions.

Q1. The sum of the two smaller sides of a triangle must be less than the length of the largest side.

Answer: False.

Q2. Every triangle has exactly three altitudes.

Answer: True.

Q3. All right-angled triangles are isosceles triangles.

Answer: False.

Q4. The triangle inequality helps us determine if a triangle with given side lengths can exist.

Answer: True.

3. Fill in the Blanks Questions.

Q1. An equilateral triangle has all its sides ______________ and all its angles ______________.

Answer: equal; equal.

Q2. The sum of the angles of a triangle is ____________.

Answer: $180^\circ$

Q3. The perpendicular drawn from a vertex to the opposite side of a triangle is called its ____________.

Answer: altitude.

Q4. If the sum of two angles in a triangle is $130^\circ$, the third angle is ____________.

Answer: $50^\circ$.
