Parallel Lines (lineas paralelas)

Parallel lines are on the same plane but they never intersect.
Las rectas paralelas están en el mismo plano, pero nunca se cortan.

Transversal

a line that intersects two or more coplanar lines at two different points
intersecta dos o más líneas en el mismo plano

transversal line t

This creates angles inside and outside the two original lines.

Esto crea ángulos dentro y fuera de las dos líneas originales.

Interior Angles (Ángulos interiores)

Exterior Angles (Ángulos exteriores)

The angles on the left are pairs that are equal. Los ángulos de la izquierda son los pares qu son iguales entre sí.

The angles on the right are pairs that add up to 180^o. Los ángulos de la derecha son los pares que suman 180^o.

Multiple Choice

Which of these is the name of the angles that lie on opposites sides of the transversal and outside of the parallel lines.
