Exercise 6.1

Question 1. In ∆PQR, D is the mid-point of QR ,
PM is ____________
PD is _____________

Is QM = MR?

Solution 1:-

PM¯¯¯¯¯¯¯¯ is altitude.
PD¯¯¯¯¯¯¯ is median.
No, QM ≠ MR.

Question 2. Draw rough sketches for the following:
(a) In ∆ABC, BE is a median.
(ib) In ∆PQR, PQ and PR are altitudes of the triangle.
(c) In ∆XYZ, YL is an altitude in the exterior of the triangle.

Solution 2:-

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

Solution 3:-
∆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, ∠ADC = 90°
Thus, AD is the median as well as the altitude of the ∆ABC. Hence Verified.
