**NCERT Solutions for Class 7 Maths Chapter 6 The Triangle and its Properties Exercise 6.1**

Ex 6.1 Class 7 Maths Question 1.

In âˆ†PQR, D is the mid-point of \(\overline{\mathrm{QR}}\) ,

\(\overline{\mathrm{PM}}\) is

\(\overline{\mathrm{PD}}\) is

If QM = MR?

Solution:

\(\overline{\mathrm{PM}}\) is altitude.

\(\overline{\mathrm{PD}}\) is median.

No, QM â‰ MR.

Ex 6.1 Class 7 MathsÂ Question 2.

Draw rough sketches for the following:

(a) In âˆ†ABC, BE is a median.

(ib) In âˆ†PQR, PQ and PR are altitudes of the triangle.

(c) In âˆ†XYZ, YL is an altitude in the exterior of the triangle.

Solution:

Ex 6.1 Class 7 MathsÂ Question 3.

Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same.

Solution:

âˆ†ABC is an isosceles triangle in which AB = AC

Draw AD as the median of the triangle.

Measure the angle ADC with the help of protractor we find, âˆ ADC = 90Â°

Thus, AD is the median as well as the altitude of the âˆ†ABC. Hence Verified.
