Question
given: quadrilateral mnol with \\( \overline { mn } \cong \overline { lo } \\) and \\( \overline { ml } \cong \overline { no } \\) prove: mnol is a parallelogram. complete the paragraph proof. we are given that \\( \overline { mn } \cong \overline { lo } \\) and \\( \overline { ml } \cong \overline { no } \\). we can draw in mo because between any two points is a line. by the reflexive property, \\( \overline { mo } \cong \overline { mo } \\). by sss, \\( \triangle mlo \cong \triangle \square \\). by cpctc, \\( \angle lmo \cong \angle \square \\) and \\( \angle nmo \cong \angle lom \\). both pairs of angles are also \\( \square \\), based on the definition. based on the converse of the alternate interior angles theorem, \\( \overline { mn } \parallel \overline { lo } \\) and \\( \overline { lm } \parallel \overline { no } \\). based on the definition of a parallelogram, mnol is a parallelogram.
- For the first blank: Since we have \(MN\cong LO\), \(ML\cong NO\), and \(MO\cong MO\) (reflexive property), by SSS (Side - Side - Side) congruence criterion, \(\triangle MLO\cong\triangle NOM\).
- For the second blank: By CPCTC (Corresponding Parts of Congruent Triangles are Congruent), \(\angle LMO\cong\angle NOM\) (because they are corresponding angles of congruent triangles \(\triangle MLO\) and \(\triangle NOM\)).
- For the third blank: \(\angle LMO\) and \(\angle NOM\) (also \(\angle NMO\) and \(\angle LOM\)) are alternate interior angles.
