Definition of vertical angles proof
WebJun 29, 2024 · Example. In the given figure, two lines AB and CD are intersecting each other and make angles 1, 2, 3 and 4. These pairs of angles are congruent i.e. equal and opposite to its corresponding angle such that: m ∠ 1 = m ∠ 3. And. m ∠ 2 = m ∠ 4. So, these are vertical angles. WebDec 29, 2024 · When two lines or line segments cross, pairs of angles that open opposite from each other are called vertical angles.
