## NCERT Solutions for Class 7 Maths Chapter 6 The Triangle and its Properties Ex 6.1

**NCERT TEXTBOOK EXERCISES**

**Question 1. In ∆PQR, D is the mid-point of $\overline { QR }$.**

**Solution:**

$\overline { PM }$ is the altitude.

PD is the median.

No! QM ≠ MR.

**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:**

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

**Solution:**

AD is the median.

AL is the altitude.

Draw a line segment BC. By paper folding, locate the perpendicular bisector of BC. The folded crease meets BC at D, its mid-point.

Take any point A on this perpendicular bisector. Join AB and AC. The triangle thus obtained is an isosceles ∆ABC in which AB = AC.

Since D is the mid-point of BC, so AD is its median. Also, AD is the perpendicular bisector of BC. So, AD is the altitude of ∆ABC.

Thus, it is verified that the median and altitude of an isosceles triangle are the same.
