Question

Can anyone help me in doing the (c) ? ASAP!

Thank you.. ​

Answer 1

Step-by-step explanation:

(c) <ABC and <BCE are corresponding angles --( AB||CE)

as sum of corresponding angles is 180°,

<ABC+ <BCE = 180°

180° can also be written as 90° + 90°

<ABC + <BCE = 90°+90°

=> two right angles

hence, proved
