Question

For constructing $\Delta$LMN exactly identical to $\Delta$ABC, choose from the options, the measurements required.

• A. LM, MN and LN
• B. MN and LN
• C. LM, MN, LN and ∠MLN
• D. LM, MN, LN, ∠MLN and ∠MNL

Answer 1

The correct option is B

MN and LN

The lengths of sides MN and LN are sufficient to construct a triangle identical to $\Delta$ABC.
Draw MN as the base and with NL as length draw an arc. Now we can draw a line perpendicular to MN, this interests the arc at L. Hence the $\Delta$MNL is constructed using the lengths of a side and a hypotenuse.
