What is a real life example of prependicular lines?
The walls of most buildings are perpendicular to the ground they are built on.
Why are right angles important to builders?
Vertical walls are important to ensure that buildings - particularly older ones - stay standing up. And a wall that is vertical is at right angles to the floor. Having said that, my children went to a school where the floorplan of each classroom was hexagonal. Furnishing it was a nightmare but it is an innovative design. An igloo probably has no right angles but most other building do.
What 4 sided figure has exactly 3 right angles?
Such a shape is impossible - in 2 dimensions. But a tetrahedron (4 sided polyhedron) can. To imagine one, look up at the corner of a room, where 2 walls meet the ceiling. There are 3 right angles there. Now measure out a distance from the corner along each edge and put a dot there, then just connect the dots, with the fourth dot being the corner, and you have a tetrahedron with 3 right angles.
