Answer:
Step-by-step explanation:
The figure shows that in triangle NRM.
In order to make NRM a right triangle, following steps are done:
1. (Given)
2. (By the pythagorean theorem in triangle EFD)
3. From the steps one and two, the RHS is equal, therefore by substitution property.
4. Now, f=r by the square root property.
5. Now, As and and f=r, therefore, by SSS postulate , ΔNRM ≅ ΔEFD.
6. By CPCTC, angle NRM is a right angle.
