The roof and exterior walls of a house represent intersecting planes. Using the image, name all the lines that are formed by the
Bess [88]

In the possible diagram of the house, the lines formed by intersecting planes are; \overline{AG}, \overline{ AB}, \overline{AH}, \overline{GF}, \overline{ BH}, \overline{HF}, \overline{BC}, \overline{ HD}, and \overline{FE}

<h3>What are the planes and the lines formed by them on the building?</h3>

The diagram found in a similar question has points <em>A</em>, G, B, H, and F on the roof.

The points on the walls of the house are; B, H, F, C, D, and E

A plane in Euclidean geometry is a surface that is flat, such that a line that connects two points on it lie completely on the plane.

A plane can be identified by three non collinear points that lay on it.

A line is a figure that does not have a curvature, width or depth, and it is infinitely long.

The planes on the roof are; ABH and AGHF

The planes on the walls of the house are; BCDH, and HDCF

The lines that are formed by the intersecting planes are therefore;

On the roof;

  • \overline{AG},  \overline{ AB},  \overline{AH}, \: \overline{GF},

Between the roof and the walls of the house;

  • \overline{BH},  \overline{HF}

Between the two sides of the walls;

  • \overline{BC},  \overline{ HD},  \overline{FE}
