## Gujarat Board Textbook Solutions Class 7 Maths Chapter 6 The Triangles and Its Properties Ex 6.1

Question 1.
In āPQR, D is the mid-point of $$\overline{Q R}$$.
$$\overline{P M}$$ is _______
PD is _______
Is QM = MR?

Solution:
PM is an altitude of āPQR.
PD is a median of āPQR.
No, QM ā  MR.

Question 2.
Draw rough sketches for the following:
(a) In āABC, BE is a median.
(b) In āPQR, PQ and PR are altitudes of the triangle.
(c) In āXYZ, YL is an altitude in the exterior of the triangle.
Solution:
(a) In the adjoining figure, $$\overline{B E}$$ is a median of AABC.

(b) In right āQPR, $$\overline{P Q}$$ and $$\overline{P R}$$ are altitudes of the triangle.

(c) In the following figure, $$\overline{Y L}$$ is an altitude of āXYZ.

Question 3.
Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same. Solution: In the adjoining figure, āABC is an isosceles triangle having AB = AC.
Draw its median AD. Now, with the help of a protractor, measure the ā ADB.
We find that

Thus, $$\overline{A D}$$ is the median as well as an altitude of āABC.
