If in the figure a||b and c||d, then name the angles that are congruent to (i) ∠1 (ii) ∠2.

Answer»

Hi ,

It is given that a // b and C // d

<1 = <3 ( vertically opposite angles )

<1 = <5 ( corresponding angles )

<1 = <9 ( corresponding angles )

Also

<1 = <3 = <5 = <7 ;

<1 = <11 = <9 = <13 = <15

Similarly ,

<2 = <4 = <6 = <8

Also

<2 = <10 = <12 = <14 = <16

I hope this helps you.
