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.

Why are obtuse angles important in tesselation?
Obtuse angles are no more important than acute or right angles. The commonest tessellation uses squares (or rectangles) and these have right angles - not obtuse.
Who discovered the right triangles?

Why is the theorem important?
to find the angles and sides of a right traingle
How do you apply angles to the real world?
