Karnataka State Syllabus Class 7 Maths Chapter 6 The Triangles and Its Properties Ex 6.1
Question 1.
In ∆PQR, D is the mid-point of \(\overline{\mathbf{Q R}}\) \(\overline{\mathbf{P M}}\) is ___
Solution:
\(\overline{\mathbf{P M}}\) is the altitude of the ∆PQR
∆ PQR
\(\overline{\mathbf{P D}}\) is ___.
\(\overline{\mathbf{P D}}\) is the median of the ∆ PQR
Is QM = MR?
No, QM ≠ MR ?
Question 2.
Draw rough sketches for the following:
Solution:
a) In ∆ ABC, BE is a median
b) In ∆ PQR, PQ and PR are altitudes of the triangle.
c) In ∆XYZ, YL is an altitude in the exterior of the triangle.
Question 3.
Verify by drawing a diagram if the median and altitude of an isosceles triangle can be same.
Solution:
In the ∆PQR
PQ = PR
PM is the Median (∵ QM = MR)
PM is the altitude. (∵ PMR = 90°)
∴ In this isosceles triangle median and altitude are the same. (proved / verified).
