Special Right Triangles
edit30-60-90
editA pattern is shown here:
- Only if 30 is the vertex angle and 60 is the other angle apart from 90 and 30.
- a=4, other leg=4√3, hypotenuse= 8
- a=9, other leg=9√3, hypotenuse= 18
- other leg=8√3, a=8, hypotenuse 16
..and so on and so forth. EXCEPT!
Special Cases
edit45-45-90
editEach of these digits separated by a dash is angle degrees. The two base angles are congruently 45 while the vertex angle is 90.
So, if a= 6, then other leg is 6 and the hypotenuse 6√2... simple and easy pattern you can see here. If:
- a= 10, other leg= 10, hypotenuse= 10√2
- a= 13, other leg= 13, hypotenuse = 13√2
- hypotenuse= 9√2, other leg and a= 9
- hypotenuse= 689√2, other leg and 1= 689
..and so on and so forth. EXCEPT!
