Question

Construct a triangle $ABC$, in which $AB=5.5cm,AC=6.5cm$ and $\angle BAC={70}^{\circ }$.
If the stpes of construction are given as below the answer the following question:

Which is the 2nd step of construction?
1) At $A$, construct a line segment $AE$, sufficiently large, such that $\angle BAC$ at ${70}^{\circ }$, use protractor to measure ${70}^{\circ }$
2) Draw a line segment which is sufficiently long using ruler.
3) With $A$ as centre and radius $6.5cm$, draw the line cutting $AE$ at C, join $BC$, then $ABC$ is the required triangle.
4) Locate points $A$ and $B$ on it such that $AB=5.5cm$.

• A. 1
• B. 2
• C. 3
• D. none of the above

Answer 1

The correct option is D none of the above

Below are the correct steps.

1. Draw a line segment which is sufficiently long using ruler.
2.Locate points $A$ and $B$ on it such that $AB=5.5cm$

3.At $A$ construct a line segment $AE$ , sufficiently large, such that $\angle BAC={70}^{\circ }$, use protractor to measure 70°.

4. With $A$ as centre and radius $6.5cm$ draw the line cutting $AE$ at $C$, join $BC$ then $ABC$ is the required triangle.

Hence, (D) will be correct answer.
