NCERT solutions for Maths Triangles and its Properties ## NCERT Solutions for Class 7 Maths Triangles and its Properties

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 ? 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.

(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.

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. ## NCERT Solutions for Class 7 Maths Exercise 6.1
