Transversal of parallel lines
Key Notes:
A transversal is a line that intersects two other lines.
Two angles formed by a transversal crossing two lines are corresponding angles if they are in matching corners.
Two angles are supplementary angles if their measures add up to 180°.
∠ABD and ∠DBC are supplementary angles.
Learn with an example
Check each pair of angles.
∠OPM and ∠LMP are not corresponding angles. They are not in matching corners.
∠OPM and ∠LMK are corresponding angles. They are in matching corners.
∠OPM and ∠OPR are not corresponding angles. They are not in matching corners.
∠OPM and ∠NMP are not corresponding angles. They are not in matching corners.
First find ∠FEH.
Check each pair of angles.
∠FEH and ∠DEH are supplementary angles. Their measures add up to 180°.
∠FEH and ∠DEC are not supplementary angles. Their measures do not add up to 180°.
∠FEH and ∠GHE are not supplementary angles. Their measures do not add up to 180°.
∠FEH and∠ IHJ are not supplementary angles. Their measures do not add up to 180°.
First find ∠LKH.
Check each pair of angles.
∠LKH and∠ LKM are supplementary angles. Their measures add up to 180°.
∠LKH and ∠JKM are not supplementary angles. Their measures do not add up to 180°.
∠LKH and ∠GHK are not supplementary angles. Their measures do not add up to 180°.
∠LKH and ∠IHF are not supplementary angles. Their measures do not add up to 180°.
