Class –VII Mathematics (Ex. 6.1)

Question 1.In {tex}\Delta {/tex}PQR, D is the mid-point of {tex}\overline {{\text{QR}}} .{/tex}

{tex}\overline {{\text{PM}}} {/tex} is _______________

PD is ________________

Is QM = MR ?

Answer:

Given: QD = DR

{tex}\therefore {/tex} {tex}\overline {{\text{PM}}} {/tex} is altitude.

PD is median.

No, QM {tex} \ne {/tex} MR as D is the mid-point of QR.

Question 2.Draw rough sketches for the following:

  1. In {tex}\Delta {/tex}ABC, BE is a median.
  2. In {tex}\Delta {/tex}PQR, PQ and PR are altitudes of the triangle.
  3. In {tex}\Delta {/tex}XYZ, YL is an altitude in the exterior of the triangle.

Answer:

(a) Here, BE is a median in {tex}\Delta {\text{ABC}}{/tex} and AE = EC.

(b) Here, PQ and PR are the altitudes of the {tex}\Delta {/tex}PQR and RP {tex} \bot {/tex} QP.

(c) YL is an altitude in the exterior of {tex}\Delta {/tex}XYZ.

Question 3.Verify by drawing a diagram if the median and altitude of a isosceles triangle can be same.

Answer:

Isosceles triangle means any two sides are same.

Take {tex}\Delta {\text{ABC}}{/tex} and draw the median when AB = AC.

AL is the median and altitude of the given triangle.
