Question

right angle theorem in full deatails

Answer 1

Answer:

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

Answer 2

Answer :

Proof of Right Angle Triangle Theorem

Theorem:In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. Hence the theorem is proved.

example :

Proof: We have a Δ ABC in which AC2 = AB2 + BC2
