Question 1, 2, 3, 4 | Page 170, 171 | Class 7 | Chapter 7 | A Tale of Three Intersecting Lines
In this video, we solve Figure it Out Questions 1, 2, 3 and 4 from Page 170 of Chapter 7 – A Tale of Three Intersecting Lines, Class 7 Ganita Prakash (CBSE). These questions take students deeper into triangle construction, including altitudes, right-angled triangles, and exploring whether certain angle combinations are possible. Students also investigate whether equilateral and isosceles triangles can be constructed with right or obtuse angles. 📘 Figure it Out – Page 170 Question 1: Construct triangle ABC with: • BC = 5 cm • AB = 6 cm • CA = 5 cm Then construct the altitude from A to BC. Question 2: Construct triangle TRY with: • RY = 4 cm • TR = 7 cm • ∠R = 140° Then construct the altitude from T to RY. Question 3: Construct a right-angled triangle ABC where: • ∠B = 90° • AC = 5 cm How many different triangles can be made using these measurements? (Explore all possible values of angles ∠A and ∠C.) Question 4: By actual construction, explore whether it is possible to draw: • an equilateral triangle that is (i) right-angled or (ii) obtuse-angled • an isosceles triangle that is (i) right-angled or (ii) obtuse-angled ▶ Constructing triangles from side and angle combinations ▶ Drawing altitudes to given sides ▶ Exploring uniqueness of triangles with right angles ▶ Understanding limitations of triangle types (right, obtuse, equilateral, isosceles) ▶ Strengthening construction accuracy and geometric reasoning This video gives students hands-on experience with geometric constructions and helps them understand which triangle types are mathematically possible.
