Triangle congruence and similarity
What is the flaw in the student's proof? Justification 4 should be "AB ÷ AD = AB ÷ AC because triangle ABC is similar to triangle ABD." Justification 1 should be "Angle ABC = Angle BCD and Angle BCA = Angle DBC." Justification 2 should be "BC ÷ DC = AC ÷ BC because triangle ABC is similar to triangle BDC." Justification 3 should be "Angle ABC = Angle ADB and Angle BAC = Angle BAD."
@ganeshie8 I don't get this one ;/
|dw:1393350721762:dw|
first two statements are about using : \(\triangle ABC \sim \triangle BDC\)
there is no flaw in those statemetns
lets look a bit closely at statement 3
|dw:1393350999487:dw|
say, that angle = \(\alpha\)
if u set up the angles correctly u will get : Justification 3 should be "Angle ABC = Angle ADB and Angle BAC = Angle BAD."
oh ok thank you so much and sorry... openstudy is kinda acting crazy for me
same here... it is acting up from last couple of hours lol
i see all oranges.. and lag..
yessss !! me too haha
