PM is ______________________

PD is _______________________

Is QM = MR ?

 


  1. Draw rough sketch for the following:
  • In ∆ABC, BE is the median
  • In ∆PQR, PQ and PR are altitudes of the triangle.
  • In ∆XYZ, YL is an altitude in the exterior of the triangle.

  1. Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same.
