Question

Prove that if two parallel lines are intersected by a transversal, then prove that the angle bisectors of corresponding angles are parallel to each other​

Answer 1

I don't know if you remember me but I was just wondering if you had any types of human thoughts

Answer 2

Step-by-step explanation:

Given: AB and CD are two parallel lines and transversal EF intersects then at G and H respectively. GM and HN are the bisectors of two corresponding angles ∠EGB and ∠GHD respectively.

To prove: GM∥HN

Proof:

∵AB∥CD

∴∠EGB=∠GHD (Corresponding angles)

∠EGB=

∠GHD

⇒∠1=∠2

(∠1 and ∠2 are the bisector of ∠EGB and ∠GHD respectively)

⇒GM∥HN

(∠1 & ∠2 are corresponding angles formed by transversal GH and GM and HN and are equal.)

Hence, proved.
