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.

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.

Ok, so do you understand what we are trying to prove?

- anonymous

no i dont

- malcolmmcswain

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.

- anonymous

But it says whats the missing information from the chart that i sent.
