Can Kayla conclude that and are similar? Why or why not?
@mhchen
Yes by Angle-Angle Postulate |dw:1547927754579:dw| They are similar
Explanation for part a
Just the Angle-Angle postulate. There's a right-angle for both of them, and also vertical angles
Blank 3: width of the river blank 4: explanation for b
|dw:1547928127889:dw| can you solve for x
it is x= 375/4
okay so yeah, that'd be the width of the river. 375/4 = 93.75ft
For the explanation part: |dw:1547928697482:dw| The ratio I used was that each fraction is from the same triangle. And the numerators and denominators of each fraction is a side that corresponds with the similar side on the other triangle.
ok thank you for that one
@dude @mhchen
Could you attempt to fill in some answers first?
Sure
it's given for the first one ?
yes
i'm having trouble with others
2nd one is Definition of Midpoint. A midpoint divides a segment into 2 congruent segments.
It's been a while since I've done geometry proofs, I can't remember all the theorems or postulates anymore. You gotta ask someone that's closer to your grade.
