NCERT Solutions for Class 7 Maths Chapter 6 The Triangle and its Properties Ex 6.1 (Rationalised Contents)
Ex 6.1 Class 7 Maths Question 1.
In ∆PQR, D is the mid-point of QR.
PM is ____________.
PD is ____________.
(a) In ∆ABC, BE is a median.
(b) In ∆PQR, PQ and PR are altitudes of the triangle.
(c) In ∆XYZ, YL is an altitude in the exterior of the triangle.
Draw the median AD of the triangle.
Measure the angle ADC with the help of protractor. We find, ∠ADC = 90°.
Thus, AD is the median as well as the altitude of the ∆ABC. Hence Verified.
PD is ____________.
Is QM = MR?
Solution:
PM is altitude.
PD is median.
No, QM ≠ MR. Because D is the mid-point of QR.
Ex 6.1 Class 7 Maths Question 2.
Draw rough sketches for the following:(a) In ∆ABC, BE is a median.
(b) In ∆PQR, PQ and PR are altitudes of the triangle.
(c) In ∆XYZ, YL is an altitude in the exterior of the triangle.
Solution:
Ex 6.1 Class 7 Maths Question 3.
Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same.Solution:
Draw an isosceles triangle ∆ABC in
which AB = AC.
Measure the angle ADC with the help of protractor. We find, ∠ADC = 90°.
Thus, AD is the median as well as the altitude of the ∆ABC. Hence Verified.
