Group Title
Given: In ∆ABC below,BD over BA equals BE over BC .
Prove: segment DE is parallel to segment AC
The flow chart proof with missing statements and reasons proves that if a line intersects two sides of a triangle and divides these sides proportionally, the line is parallel to the third side.
Which statement and reason can be used to fill in the numbered blank spaces?
Answers
1. ∡BDE ≅ ∡BAC
2. Corresponding Parts of Similar Triangles
1. ∡BDE ≅ ∡BCA
2. Alternate Exterior Theorem
1. ∡BDE ≅ ∡BAC
2. Corresponding Angles Postulate
1. ∡BDE ≅ ∡BCA
2. Corresponding Parts of Similar

Converse of Corresponding Angles Postulate says, if corresponding angles are equal, then the lines are parallel

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.3
they are corresponding angles, cuz \(\triangle BDE\) and \(\triangle BAC\) are similar,

Yes, that makes the 3rde choice make sense.

now can we say they are congruent, cuz corresponding angles of similar triangles are congruent ?

it cannot be 3rd cuz, we dont know lines are parallel yet

notice the justification for 3rd one
