Question

find missing legnth

Answer 1

its a kite !

Answer 2

well i know that

Answer 3

i thought that would make DG the same length bc they are opposites

Answer 4

in kite, "nonvertex angles" are congruent, and the sides opposite them also congruent.

Answer 5

F and D are nonvertex angles here

Answer 6

that gives, EF = DE, and FG = GD

Answer 7

oh...

Answer 8

im sure u didnt get this clearly enough

Answer 9

so the answer was B bc DE and EF are equal right?

Answer 10

Yes answer is EF = 6 = DE

Answer 11

i really appreciate you explaining it to me :)

Answer 12

np :)

Answer 13

the sides opposite to the diagonal thats bisected are congruent

Answer 14

there is another simple way to see this, without using kite. using oly the triangles if you're up for it :)

Answer 15

sure

Answer 16

look at the pic, lets say, the diagonals are intersecting at O

Answer 17

the two small triangles OFE and ODE are congruent by HL theorem.

so by CPCTC, FE = DE. Done.

Answer 18

CPCTC what is that

Answer 19

its aan acronym

Answer 20

CPCTC = Corresponding Parts of Congruent Triangles are Congruent

Answer 21

oh ok that makes sense

Answer 22

it simply says this : when two triangles are congruent, then their corresponding parts are congruent

Answer 23

great :)
