EXERCISE – 6.1
Q1. In ΔPQR , D is the mid point of QR .
PM is __Altitude _______.
PD is __Median________.
Is QM = MR ?
No, QM = MR is not equal.
Q2. Draw a rough sketches for the following:
(a) In ΔABC , BE is an median
(b) In ΔPQR, PQ and PR are altitudes of the triangle.
(c) In ΔXYZ, YL is an altitude in the exterior of the triangle.
(a) A median connects a vertex of a triangle to the triangle to the mid – points of the opposite side.
(b) An altitude has one end
(c) In the figure we may observe that for ΔXYZ , YL is an altitude drawn exteriorly to side XZ which is extended up to point L.
Q3. Verify by drawings a diagram if the median and altitude of an isosceles triangle can be same.
Draw a line segment PS Altitude BC. It is an altitude for this triangle. Here we observe that length of QS and SR is also same. So Ps is also a median of this triangle.
