Given

at #2. why are the triangles BAD and BCD right triangles?

- anonymous

? because they have right angles

- anonymous

90 degrees

- sirm3d

that's exactly the definition of a right triangle. Reason #2: Definition of a Right Triangle

thnxs now how do i get number three

- sirm3d

what do think is reason #3?

- anonymous

umm they are congruent

- anonymous

?

- sirm3d

it is part of the given.

- anonymous

so #3 is part of a given

- sirm3d

Reason #3: Given

- sirm3d

there are two given informations. (1) the right angles A and C, and (2) the congruent segments AB and CB. so you can use the reason "Given" twice.

oh okay i get it now statement 4 this is a little harder

- anonymous

? :-(

- anonymous

help plz

- sirm3d

the reflexive property is used when something is congruent/equal to itself, like \(\overline{PQ} \cong \overline{PQ}\) or \(\angle X \cong \angle X\)
in the problem, what triangle part is used or common to the two triangles?

- anonymous

Triangle BCD?

- sirm3d

what is the common part, maybe an angle or a segment, of the two triangles?

- sirm3d

BD

- anonymous

segment BD

- sirm3d

right. \[\overline {BD} \cong \overline {BD}\]

- anonymous

5 is triangle BAD=BCD am i right

- sirm3d

that goes into statement #5.

- sirm3d

right it is. and for the reason?

- anonymous

I already have the reason done HL

- anonymous

how about statement 6

- sirm3d

the last line is what you were supposed to prove, \(\overline{AD}\cong \overline{CD}\)

- anonymous

thats what i thought thnxs so much for ur patience
