ANGLE PAIRS
VERTICAL ANGLES: the two angles opposite ("across") from each other formed
when two lines intersect.
THEOREM : VERTICAL ANGLE THEOREM
Vertical angles are congruent.
PLANNING A PROOF
PLANNING A PROOF
THEOREM : If two angles are supplements of congruent angles ( or of the same angle), then the two angles are congruent.
PLANNING A PROOF
THEOREM : If two angles are complements of congruent angles ( or of the same angle), then the two angles are congruent.
