Two Vertical Angles Form A Linear Pair - Web vertical angles are congruent. Web if two angles form a linear pair, the angles are supplementary, whose measures add up to 180°. Hence, a linear pair of angles. Web for abc above, ∠a+∠c+∠abc=180°. Also, ∠abc and ∠dbc form a linear pair so, ∠abc + ∠dbc = 180° substituting the second. ∠1 and ∠3 are vertical angles ∠2 and ∠4 are vertical. Web two angles are vertical angles, if their sides form two pairs of opposite rays. Vertical angles, such as ∠1 and ∠2, form linear pairs with the same angle, ∠4, giving m∠1 +.
