I'm doing Florida virtual school and i am on module 3.03 quiz. can anyone help me?
I can.. I am in flvs senior
Okay thank you. Have you completed this quiz yet?
i did that 2 years ago. I have completed all my work for this year.
So can you help me with it? I can copy and past the quiz here?
post it
Triangle ABC is shown below: Triangle ABC. Line passes through points D, B, and E Given: ΔABC Prove: All three angles of ΔABC add up to 180°. The flowchart with missing reason proves the measures of the interior angles of ΔABC total 180°: Top path, by Construction, line segment DE is parallel to line segment AC. By Alternate Interior Angles, angle EBC is congruent to angle BCA. By Substitution, the sum of the measures of angles BCA, CBA, and BAC equals 180 degrees. Next path, by Construction, line segment DE is parallel to line segment AC. By space labeled 1, angle DBA is congruent to angle BAC. By Substitution, the sum of the measures of angles BCA, BCA, and BAC equals 180 degrees. Next path, by Construction, line segment DE is parallel to line segment AC. By Definition of a Straight Angle, the measure of angle EBD equals 180 degrees. By Substitution, the sum of the measures of angles EBC, CBA, and DBA equals 180 degrees. Bottom path, by Construction, line segment DE is parallel to line segment AC. By Angle Addition Postulate, the sum of the measures of angles EBC, CBA, and DBA equals the measure of angle EBD. By Substitution, the sum of the measures of angles EBC, CBA, and DBA equals 180 degrees. Which reason can be used to fill in the numbered blank space?

That is question one
@malcolmmcswain
@Hayhayz
@JoeDeWise
I have no idea, sorry.
@ZelArts
@Mehek14
both offline thats ok
Is there an image that goes with the problem?
@Tiffanyrose239 u there?
Yes
Wrong attatchment
This is the one for that question. @malcolmmcswain
Gracias. :3
In ΔABC shown below, ∠BAC is congruent to ∠BCA: Triangle ABC, where angles A and C are congruent Given: Base ∠BAC and ∠ACB are congruent. Prove: ΔABC is an isosceles triangle. When completed (fill in the blanks), the following paragraph proves that Line segment AB is congruent to Line segment BC making ΔABC an isosceles triangle. Construct a perpendicular bisector from point B to Line segment AC. Label the point of intersection between this perpendicular bisector and Line segment AC as point D: m∠BDA and m∠BDC is 90° by the definition of a perpendicular bisector. ∠BDA is congruent to ∠BDC by the definition of congruent angles. Line segment AD is congruent to Line segment DC by by the definition of a perpendicular bisector. ΔBAD is congruent to ΔBCD by the _______1________. Line segment AB is congruent to Line segment BC because _______2________. Consequently, ΔABC is isosceles by definition of an isosceles triangle. corresponding parts of congruent triangles are congruent (CPCTC) the definition of a perpendicular bisector the definition of a perpendicular bisector the definition of congruent angles the definition of congruent angles the definition of a perpendicular bisector Angle-Side-Angle (ASA) Postulate corresponding parts of congruent triangles are congruent (CPCTC)
Ok, so do you understand what we are trying to prove?
no i dont
Ok, so, basically we are trying to prove that if we add all the interior angles of the triangle, they will add up to 180 degrees.
But it says whats the missing information from the chart that i sent.

Options?
i posted them
Hold on, I have to leave.
I'll be right back.
ok
