Construction Carpenters use parallel wall studs in building supports for walls. Describe three ways a carpenter could guarantee that the wall studs \(\overline{A B} \text { and } \overline{C D}\) are parallel Equation Transcription: Text Transcription: overline AB and overline CD

In the Hands-On Geometry activity on page 162, you constructed a line through a point P parallel to a line . In 1795, Scottish mathematician John Playfair (1748–1819) provided the modern version of Euclid’s famous Parallel Postulate. If there is a line and a point not on the line, then there exists exactly one line through the point that is parallel to the given line. Explain the meaning of exactly one in the postulate. If you try to draw two lines parallel to a given line through a point not on the line, what happens?
