Question

explain please urgently ​

Answer 1

Step-by-step explanation:

/_LMN = 90° , /_LKN = 90°

so, now prove that ,

∆KLM ≈ ∆ KNM

/_LKM = /_RMN ( alternative angles)

MK (common side )

/_RML = /_RMN

therefore , according to ASA congruency ..

now, ∆LRM ≈ ∆NRM

MR ( common side )

ML= MN ( by above derivation )

/_MLK=/_MNK ( opposite angles)

therefore, ∆LRM ≈ ∆NRM proved..

by this we can say that ,

LR = RN

so, R is the mid point !!
