NCERT Class 7th Mathematics Chapter 6 – The Triangle and its properties – Exercise 6.1 Solutions

1. In ∆ PQR, D is the mid-point of QR .
PM is _____Altitude____________.
PD is _______Median__________.
Is QM = MR? 

Ans: No, QM is not equal to MR.

2. Draw rough sketches for the following:
(a) In ∆ABC, BE is a median.

Ans: BE is a median because it divides AC in two equal parts AE and EC.

(b) In ∆PQR, PQ and PR are altitudes of the triangle.
(c) In ∆XYZ, YL is an altitude in the exterior of the triangle.

Ans: YL is an altitude drawn by extending XZ to L.

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

Ans: Draw AD perpendicular on BC, so AD is altitude. Also AD divides BC into two equal parts BD and DC, so AD is a median.
