Question 1.

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

Solution:

We have,

A is neither in the interior nor in the exterior of the triangle ABC. It is a vertex.

Question 2.

(a) Identify three triangles in the figure.

(b) Write the names of seven angles.

(c) Write the names of six line segments.

(d) Which two triangles have ∠B as common?

Solution:

(a) The three triangles are ∆ABC, ∆ABD, ∆ADC

(b) 7 angles are ∠ADB, ∠ADC, ∠ABD, ∠ACD, ∠BAD, ∠CAD, ∠BAC

(c) 6 line segments are \(\overline{A B}\), \(\overline{A C}\), \(\overline{A D}\), \(\overline{B D}\), \(\overline{D C}\), \(\overline{B C}\)

(d) Two triangles having ∠B as common are ∆ABC, ∆ABD
