NCERT Solutions for Class 6 Maths Chapter 4: Basic Geometrical Ideas - Exercise 4.4

Exercise 4.4

1. Draw a rough sketch of a triangle $ABC$. Mark point $P$ in its interior and a point $Q$ in its exterior. Is the point $A$ in its exterior or in its interior?

Ans: A three sided polygon with three edges is known as a triangle.

Draw a triangle $ABC$ and label a point $P$ inside the triangle and a point $Q$ outside the triangle.

The above figure shows that point $A$ is neither interior nor exterior of the triangle.

$A$ is the vertex of the triangle $ABC$.

2. Use the figure to write the following:

a) Identify three triangles in the figure.

Ans: A three sided polygon with three edges is known as a triangle.

It is required to identify three triangles from the given figure.

Use the definition of triangle to find the triangles. Identify the three sided polygons in the figure.

Therefore three triangles in the given figure are $\Delta ABC$, $\Delta ABD$ and $\Delta ADC$.

b) Write the names of seven angles.

Ans: Angle of a triangle is the figure formed between two sides of a triangle.

It is required to identify seven angles in the given figure.

Use the definition of angle of triangle to find the angles. 

Therefore seven angles in the given figure are $\angle ABC$, $\angle ABD$, $\angle ADB$, $\angle ADC$, $\angle ACD$, $\angle ACB$, $\angle BAC$.

c) Write the names of six line segments.

Ans: A line segment is a part of a line that has two fixed endpoints and cannot be extended.

It is required to identify six line segments in the given figure.

Use the definition of line segments to identify the line segments in the given figure. 

Therefore six line segments in the given figure are $\overline {AB} $, $\overline {AC} $, $\overline {AD} $, $\overline {BD} $, $\overline {DC} $ and $\overline {BC} $.

d) Which two triangles have $\angle B$ as common?

Ans: Angle of a triangle is the figure formed between two sides of a triangle.

It is required to identify which two triangles in the given figure have $\angle B$ as a common angle.

Use the definition of angle of triangle to find the angles. 

See triangle $\Delta ABC$ and $\Delta ABD$. Both the triangles have a common vertex $B$.

Therefore both the triangles $\Delta ABC$ and $\Delta ABD$ have common angles $\angle ABD$ and $\angle ABC$.
