Question

Length of sides of a $△ABC$ is $AB=5cm$, $AC=3cm$ and $BC=4cm$. If the construction of the triangle formed by these three sides include following steps, then answer the following question:

Which of the following is the first step of construction?

Steps of construction:

Step 1. Now join $A$ to $C$ and $B$ to $C$.

Step 2. Assuming $A$ a centre draw an arc of radius $3cm$

Step 3. Now assuming $B$ as centre draw an arc of $4cm$ intersecting the previous arc at $C$.

Step 4. Draw a line segment $AB=5cm$

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

Steps of construction:

Step 1. Draw a line segment $AB=5cm$

Step 2. Assuming $A$ a centre draw an arc of radius $3cm$

Step 3. Now assuming $B$ as centre draw an arc of $4cm$ intersecting the previous arc at $C$.

Step 4. Now join $A$ to $C$ and $B$ to $C$.

Hence, (D) will be correct.
