a, b, c, and d are distinct lines in the same plane. Exercises 14-21 show different combinations of relationships between a and b, b and c, and c and d. For each combination of the three relationships, how are a and d related? a || 6,6 || C, Cidif anyone could give me the formula to solve this or a explanation that would be amazing! thank you.

Respuesta :

it is given

a II b and b II c

and c perpendicular to d

as a is parallel to b and b is parallel to c ,

so a would-be parallel to c also, but c is perpendicular to d

so, a also will be perpendicular to d.

so the answer is

[tex]a\perp d[/tex]

a is perpendicular to d
