Question

AD is median andBL ,CM are perpendiculars drawn from B,C resp. on AD amdAD produced . proveBL=CN

Answer 1

Answer:

inΔBDL and ΔCDM,

∠BLD=∠CMD(both equal to 90°)

∠BDL=∠CDM (vetically opposite angles are equal)

BD=CD(AD is median)

∴ΔBDL≡ΔCDM(AAS conguency)

⇒BL=CM(cpct,corresponding parts of congruent triangles)

hence proved
