Question

EXERCISE 6.1 1. In A PQR, D is the mid-point of QR. PM is PD is Is QM = MR? R M D 2. Draw rough sketches for the following: (a) In AABC, BE is a median. (b) In APQR, PQ and PR are altitudes of the triangle. (c) In AXYZ, YL is an altitude in the exterior of the triangle. 3. Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same. 6.4 EXTERIOR ANGLE OF A TRIANGLE AND ITS PROPERTY​

Answer 1

Step-by-step explanation:

According to this model, PM is perpendicular on QR.

Also, PD divides QR into equal parts as D is the mid-point of QR.

Therefore, PM is altitude.

Also, D is the mid-point of QR.

Therefore, QD = DR and hence PD is the median

Yes, QM ≠ MR because D is the mid-point of QR.
