2. Draw rough sketches for the following:
(a) In ΔABC, BE is a median.
We know that the median connects a vertex of a triangle to the mid-point of the opposite side.
(b) In ΔPQR, PQ and PR are altitudes of the triangle.
We know that altitude has one end point at a vertex of the triangle and the other on the line containing the opposite side.
(c) In ΔXYZ, YL is an altitude in the exterior of the triangle.
In this figure we observe for ΔXYZ, i.e YL is an altitude drawn exteriorly to side XZ which is extended up to point L.
