i have no absaloute clue what so ever
Traditionally in the western world, walls in buildings are erected to be perfectly vertical. Rooms are constructed usually with square corners. The requirement for a building being perfectly vertical is all the more critical in high rise buildings and sky scrapers. Hence the right triangles are used in laying brick, cutting wood etc.

Right angles are equal to 90 degrees; making it completely straight. They are used in constructions so the builder can see if the building is completely straight (vertically). If the building is not 90 degrees, it is likely to collapse.
The Pythagorean Theorem is a statement about triangles containing a right angle. The Pythagorean Theorem states that:"The area of the square built upon the hypotenuse of a right triangle is equal to the sum of the areas of the squares upon the remaining sides."
No. The Pythagorean theorem applies only to right triangles...those containing a right angle (90 degrees).
Pythagoras' theorem can be used for right-angled triangles. Using the theorem, you are able to calculate what the length of one side of a triangle is.
Sine is a mathematical formula used in right angled triangles. It is Opposite/Hypotenuse . Opposite being the angle opposite the angle of your choice and Hypotenuse being the longest side in your right angled triangle.
