Question

Complete the proof given below.

Answer 1

Given that the opposite sides of a parallelogram are congruent, a diagonal

of the parallelogram forms two congruent triangles.

The correct options to complete the proof are;

• Opposite sides of a parallelogram; ABCD is a parallelogram

• Reflexive property of congruency

• SSS

Reasons:

The completed two column proof is presented as follows;

Statement  ${}$                                  Reason

1. ABCD is a parallelogram  ${}$       1. Given

2. $\overline{AB}$ ≅ $\overline{DC}$ and $\overline{BC}$ ≅ $\overline{DA}$  ${}$      2. Opposite sides of a parallelogram

3. $\overline{AC}$ ≅ $\overline{CA}$    ${}$                             3. Reflexive property of congruency

4. ΔABC ≅ ΔCDA     ${}$                   4. SSS

The correct options are therefore;

Opposite sides of a parallelogram; ABCD is a parallelogram

Reflexive property of congruency

SSS;

Reason 2. Opposite sides of a parallelogram, which is based on the

properties of a parallelogram and that ABCD is a parallelogram.

Reason 3. The reflexive property of congruency, states that a side is

congruent to itself.

Reason 4. SSS is an acronym for Side-Side-Side, which is a congruency

postulate that states that if the three sides of one triangle are equal to the

three sides of another triangle, then the two triangles are congruent.
