FG bisects DB 3. To Prove: ∆ABC ≅ ∆CDA AC is a diagonal of parallelogram ABCD which divides it into two triangles, namely, ∆ABC and ∆CDA. AB BC Side ACD BCD Reasons 2. so far ive proven that ABC≅ CDA by SSS and opposite sides are congruent. 3. lines form right . ABCD is a parallelogram 2. 6. The parallelogram shown represents a map of the boundaries of a natural preserve. Theorem 8.3 If each pair of opposite sides of a quadrilateral is equal, then it is a parallelogram. A parallelogram is defined as a quadrilateral where the two opposite sides are parallel. Since this a property of any parallelogram, it is also true of any special parallelogram like a rectangle, a square, or a rhombus,. Since the diagonal AC is the same for triangles ABC and CDA, we can use the SSS theorem to prove that triangle ABC is congruent to triangle CDA (side AB ≅ side CD, side AD ≅ side BC, and side AC ≅ side AC). 4) If in a quadrilateral, each pair of opposite angles is equal then it is a parallelogram.
