Parallelogram Angle Relationships

Vocabulary flashcards covering the properties of consecutive and opposite angles in a parallelogram.

Consecutive Angles in a Parallelogram

Angles in a parallelogram that are supplementary to each other, such as Angle C measuring $70^{\circ}$ and consecutive Angle D measuring $110^{\circ}$.

Opposite Angles in a Parallelogram

Angles in a parallelogram that are congruent to each other, such as Angle J measuring $98^{\circ}$ and opposite Angle L measuring $98^{\circ}$.

Supplementary Angles in a Parallelogram

Consecutive angles in a parallelogram whose sum total $180^{\circ}$, determining Angle D to be $110^{\circ}$ when Angle C is $70^{\circ}$.

Congruent Angles in a Parallelogram

Opposite angles in a parallelogram that have equal measures, determining Angle L to be $98^{\circ}$ when Angle J is $98^{\circ}$.
