Question

ABCD is an isosceles trapezium in which AB||DC and AD||BC. DM and CN are perpendicular to AB from D and C resp. Give reason for each of the following:-
a) Is DM = CN?
b) Is triangle ADM =~ triangle BCN?
c) Is angleA = angleB
​

Answer 1

Answer:

Solution:

In △ADE and △BCF

∠A=∠B (Base angle is same in Isosceles)

∠CFB=∠DEA=90

∘

AD=BC

△ADE≡△BCF (by ASA)
