## Access NCERT Solutions for Class 7 Maths Chapter 6 – Triangles and its properties

Exercise 6.1

Refer to page 3 for exercise 6.1 in the PDF.

1. In $\vartriangle PQR$, $D$ is the mid-point of $\overline {QR}$.

Fill the following blanks.

$\overline {PM}$ is ___________ and $PD$ is _______. Is $QM = MR$?

Ans: It is given a $\vartriangle PQR$, $D$ is the mid-point of $\ overline {QR}$. It means $QD = DR$. Since $\overline {PM}$ is perpendicular to the side $QR$ of triangle $\vartriangle PQR$, $\overline {PM}$ is the altitude of  $\vartriangle PQR$. Since $QD = DR$, $PD$ is the median of triangle $\vartriangle PQR$.

No, $QM \ne MR$ because $D$ is the mid-point of $\overline {QR}$. It means $QD = DR$.

2. Draw rough sketches for the following:

a) Draw a rough sketch of $\vartriangle ABC$, where $BE$ is a median.

Ans: A median of a triangle is a line segment that is drawn from a vertex to the opposite side of the vertex and it divides the opposite side into two equal parts. The rough sketch of $\vartriangle ABC$, where $BE$ is a median, is drawn below.

Here $BE$ is a median in $\vartriangle ABC$ and $AE = EC$.

b) Draw rough sketches of $\vartriangle PQR$, where $PQ$ and $PR$ are the altitudes of the triangle.

Ans: An altitude of a triangle is defined as a perpendicular drawn from the vertex to the line containing the opposite side of the triangle. The rough sketch of $\vartriangle PQR$, where $PQ$ and $PR$ are the altitudes of the triangle is drawn below.

c) Draw rough sketches of $\vartriangle XYZ$, where $YL$ is an altitude in the exterior of the triangle.

Ans: An altitude of a triangle is defined as a perpendicular drawn from the vertex to the line containing the opposite side of the triangle. The rough sketch of $\vartriangle XYZ$, $YL$ is an altitude in the exterior of the triangle is drawn below.

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

Ans: It is given an isosceles triangle. It is required to verify if the median and altitude of the given triangle can be the same. To do this, construct an isosceles triangle. An isosceles triangle has two equal sides.

Construct an isosceles triangle $\vartriangle ABC$ with sides$AB = AC$ and draw a median $AL$ that divides the base of the triangle into two equal parts.

From the triangle, it can be seen that the median makes a ${90^ \circ }$ angle with the base $BC$. So, $AL$ is the altitude of the triangle $\vartriangle ABC$. Hence verified, $AL$ is the median and altitude of the given triangle $\vartriangle ABC$.
