Important Questions on Class 7 Maths Chapter 6

PQR is a triangle, right angled at P. If PQ = 10 cm and PR = 24 cm, find QR.

Given: PQ = 10 cm, PR = 24 cm
Let QR be x cm.
In right angled triangle QPR, (Hypotenuse)² = (Base)² + (Perpendicular)²
[By Pythagoras theorem]
(QR)² = (PQ)² + (PR)²
x² = 10² + 24²
x² = 100 + 576 = 676
x = 26 cm
Thus, the length of QR is 26 cm.

ABC is a triangle, right angled at C. If AB = 25 cm and AC = 7 cm, find BC.

Given: AB = 25 cm, AC = 7 cm
Let BC be x cm.
In right angled triangle ACB, (Hypotenuse)² = (Base)² + (Perpendicular)²
[By Pythagoras theorem]
(AB)² = (AC)² + (BC)²
25² = 7² + x²
625 = 49 + x²
x² = 625 – 49 = 576
x = 24 cm
Thus, the length of BC is 24 cm.

About NCERT Solutions for Class 7 Maths Chapter 6

In 7 Maths Chapter 6 Triangle and its Properties, we will study about the various properties of a triangle. We know that a triangle is a simple closed curve made of three line segments. It has three vertices, three sides and three angles. It can be classified on the basis of sides and angles as follows:
1. Based on Sides: Scalene, Isosceles and Equilateral triangles.
2. Based on Angles: Acute-angled, Obtuse-angled and Right-angled triangles.
Read the following concepts before going through the chapter:
Median of a triangle is a line segment drawn form vertex to the mid-point of opposite side. So, a triangle can have three medians drawn from three vertices.
Altitude of a triangle is a perpendicular line drawn from vertex to opposite side. Like median, a triangle can have three altitudes drawn from three vertices.
An exterior angle of a triangle is equal to the sum of its interior opposite angles.
Angle sum property of Triangle: The sum of all the three interior angles of a triangle is 180°.
