1.

In the given figure. AB || CD and BC||DE.Show that angle x= angle y​

Answer»

ANSWER:

x=y

Step-by-step explanation:

We know AB||CD that means

ANGLE ABC = angle BCD

(alternate interior angles)

We know BC||DE that means

angle BCD = angle CDE

(alternate interior angles)

angle ABC = angle BCD

angle CDE = angle BCD

therefore angle ABC = angle CDE

(THINGS equal to the same thing are equal to ONE ANOTHER)

hence
