Steps for the construction of a right triangle LMN in which ∠M=90∘, MN = 4 cm and LN = 6.2 cm is given below. Choose the correct order.
1. Draw a line segment XY.
2. Construct a line segment MP, sufficiently large such that ∠NMP=90∘
3. With N as centre and radius 6.2 cm draw an arc, cutting MP at L, join NL.
4. Locate M and N on XY such that MN = 4 cm.
