## Rajasthan Board RBSE Class 6 Maths Chapter 8 Basic Geometrical Concepts and Shapes Ex 8.3

Question 1.

The road from villages Ajabgarh to Gajabgarh (RBSESolutions.com) is drawn below. Write the name of ∠1, ∠2, ∠3, ∠4.

Solution:

(i) ∠1 = Obtuse angle

(ii) ∠2 = Right angle

(iii) ∠3 = Obtuse angle

(iv) ∠4 = Reflex angle

Question 2.

Draw the following angles in your copy (RBSESolutions.com) arbitrarily and write their measurement with a protractor.

(i) Obtuse angle

(ii) Straight angle

(iii) Acute angle

(iv) Right angle

Solution:

Question 3.

Draw the following (RBSESolutions.com) angles using protractor.

(i) 45°

(ii) 90°

(iii) 72°

(iv) 105°

(v) 134°

(vi) 180°

(vii) 20°

(viii) 21°

Solution:

Question 4.

With the help of (RBSESolutions.com) compass and ruler draw the following angles :

(i) 60°

(ii) 120°

(iii) 180°

(iv) 90°

(v) 45°

Solution:

(i) Drawing ∠60°

**Step 1 :** Draw a line segment AB. Now taking a suitable radius put the tip of compasses on A and draw an arc cutting AB at point P.

**Step 2 :** Put the tip on P and draw (RBSESolutions.com) another arc of same radius intersecting the previous arc. Mark Q on pointed intersection.

**Step 3 :** Joining A and Q, we have ∠QAB = 60°.

(ii) Drawing ∠120°

**Step 1** : Continuing with the previous steps, put the (RBSESolutions.com) tip of compasses on Q and draw one more arc of the same radius, which intersects the previous are at point R.

**Step 2 :** Joining AR we get ∠RAB = 120°.

(iii) Drawing ∠180° Continuing the (RBSESolutions.com) steps of the above question (ii).

**Step 1 :** Draw an arc of the same radius with the tip of compasses on R which intersects the previous are at point S.

**Step 2 :** Joining SA, we get ∠SAB = 180°.

(iv) Drawing ∠90°

(v) Drawing ∠45°.

∠45° can be constructed by bisecting ∠90°.

Question 5.

Observe and find out the (RBSESolutions.com) similar figures In the following.

Solution:

On observing we find that (RBSESolutions.com) following figures are similar

(i) and (D)

(ii) and (C)

(iii) and (A)

(iv) and (B)

(v) and (E)
