In ΔPQR, D is the mid—point of
(i) is ______ .
(ii) PD is ______ .
(iii) Is QM = MR ?
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.
Here, it can be observed that for ∆XYZ , YL is an altitude drawn exterior to side XZ which is
extended up to point L.
3. Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same.
Draw a line segment AD perpendicular to BC . It is an altitude for this triangle. It can be observed
It the length of BD and DC is also same. Therefore, AD is also a median of this triangle.
