RS Aggarwal Class 7 Math Fifteenth Chapter Properties of Triangles Exercise 15D Solution EXERCISE 15D (1) Find the length of the hypotenuse of a right triangle, the other two sides of which measure 9 cm and 12 cm. Solution: By Pythagoras’s theorem, AB 2 = BC 2 + AC 2 or, AB 2 = 9 2 + 12 2 or, AB 2 = 81 + 144 or, AB 2 = 225 or, AB = √225 = 15 Hence, the length of hypotenuse is 15 cm. (2) The hypotenuse of a right triangle is 26 cm long. If one of the remaining two sides is 10 cm long, find the length of the other side. (3) The length of one side of a right triangle is 4.5 cm and the length of its hypotenuse is 7.5 cm. Find the length of its third side. (4) The two legs of a right triangle are equal and the square of its hypotenuse is 50.Find the length of each leg. (5) The sides of a triangle measure 15 cm, 36 cm and 39 cm. Show that it is a right-angled triangle. (6) In right ∆ABC, the lengths of its legs are given as a = 6 cm and b = 4.5 cm. Find the length of its hypotenuse. (7) The lengths of the sides of some triangles are given below. Which of them are right-angled? (i) a = 15 cm, b = 20 cm and c = 25 cm (ii) a = 9 cm, b = 12 cm and c = 16 cm (iii) a = 10 cm, b = 24 cm and c = 26 cm (8) In a ∆ABC, ∠B = 35 o and ∠C = 55 o. Write which of the following is true: (i) AC 2 = AB 2 + BC 2 (ii) AB 2 = BC 2 + AC 2 (iii) BC 2 = AB 2 + AC 2 (9) A 15-m- long ladder is placed against a wall to reach a window12 m high. Find the distance of the foot of the ladder from the wall. (10)...

Textbook Class Class 7 Subject Maths Chapter Chapter 15 Chapter Name Properties of Triangles Exercise 15D RS Aggarwal Solutions for Class 7 Chapter 15 Properties of Triangles Ex 15D Download PDF Question 1. Solution: In right triangle ABC, ∠B = 90° AB = 9cm, BC = 12cm By Pythagoras Theorem, AC² = AB² + BC² = (9)² + (12)² = 81 + 144 = 225 AC = √225 = 15 cm Question 2. Solution: In right ∆ABC, ∠B = 90° AC = 26cm, AB = 10cm By Pythagoras Theorem AC² = AB² + BC² ⇒ (26)² = (10)² + BC² ⇒ 676 = 100 + BC² ⇒ BC² = 676 – 100 = 576 = (24)² ⇒ BC = 24 cm Question 3. Solution: In right ∆ABC, ∠C = 90°, AB = 7.5cm, BC = 4.5cm By Pythagoras Theorem AB² = BC² + AC² ⇒ (7.5)² = (4.5)² + AC² ⇒ 56.25 = 20.25 + AC² ⇒ AC² = 56.25 – 20.25 = 36.00 = (6)² ⇒ AC = 6cm Question 4. Solution: In ∆ABC, ∠B = 90° Let each leg = x cm By Pythagoras Theorem, x² + x² = AC² ⇒ 2x² = 50 ⇒ x² = 25 = (5)² ⇒ x = 5 Length of each equal leg = 5cm Question 5. Solution: A triangle is a right-angled, If (Hypotenuse)² = sum of squares or other two sides If (39)²...
