Question

Quadrilateral ABCD with vertices at A(-5,-1),B (2,4),C (9, 2), and D(2,-3) is shown below.
Diagonal BD is drawn. Use coordinate geometry to prove that ABD  CDB.

Answer 1

hahah what's the proof yall

Answer 2

where's the diagram?

Answer 3

ABD  CDB?

Answer 4

What are those squares?

Answer 5

I need to prove they are eaual but I couldn't get the diagram

Answer 6

what are they?

Answer 7

angles, sides, puppies?

Answer 8

the symbol in front of ABD is unintelligible. Is it an angle symbol?

Answer 9

angle

Answer 10

Okay, here is the plan for the proof. First, draw a picture. Then, use the distance formula to measure the lengths of all the sides of the quadrilateral AND its diagonal BD. Use Side-Side-Side theorem to prove two triangles congruent. Angle ABD is congruent to angle CDB because corresponding parts of congruent triangles are congruent (CPCTC).

Answer 11

That is just the outline. You have to do the actual heavy lifting of writing the proof. Ask questions to clarify and help.

Answer 12

hmm this is to hard lol I am truly the worst at this!

Answer 13

Give it a shot, it sounds scary in math language but really writing a proof is just like climbing a mountain. The more mountains you climb the stronger you grow and the easier it is to climb new mountains ...

Answer 14

Start by drawing a picture.

Answer 15

hmmmm my brain just wants to go to sleep

Answer 16

Me too, maybe we should catch some zzz's then work on this tomorrow.

Answer 17

lol I think so! tomorrow could you give me the answer lmao XD

Answer 18
