1. In geometry, two adjacent angles formed by two intersecting lines that are supplementary (sum to 180 degrees) and share a common vertex and side
When two straight lines intersect, they create four angles, and any two adjacent angles form a linear pair.
Quando duas linhas retas se intersectam, elas criam quatro ângulos, e quaisquer dois ângulos adjacentes formam um par linear.
2. Two angles that are on a straight line and together measure exactly 180 degrees
Angles A and B form a linear pair because they are supplementary angles on a straight line.
Os ângulos A e B formam um par linear porque são ângulos suplementares em uma linha reta.
Linear pair is a fundamental concept in geometry taught in middle and high school mathematics in both the United States and Brazil. It is essential for understanding angle relationships and proofs in Euclidean geometry. The term is used exclusively in educational and technical contexts.
