Answer 2

@iGreen @phi @Zarkon @radar

Answer 3

how explain, @rileychampion365

Answer 4

d...?

Answer 5

AB + BC doesn't necessarily = DE + EC... it does equal CD + DE though

Answer 6

so I think D is incorrect / not a conclusion we can make

Answer 7

so the answer wouldnt be C it would be D?

Answer 8

yeah, that's what I recon, do u understand why tho?

Answer 9

no sir i do not

Answer 10

s'ok, do u understand the dashes on the lines?

Answer 11

yes

Answer 12

sweet, then you know line CE = CA
and line CB = CD
and angle C in the top tri = angle C in the bottom triangle

Answer 13

yes

Answer 14

notice by side-angle-side the top and bottom triangles are congruent
in the last line, if you match up corresponding sides, you see BC does not correspond to EC (BC matches with DC)

Answer 15

so the 2 triangles are equal (same side lengths and angles) , but the bottom one is reflected ... whoa... way to come over the top for the win @phi , lol ;)

Answer 16

oh okay you guys are awesome haha
