Practice (click here to print out just the practice problems)

Do at least half of the following and as many others as you need for the review (*means required problem).

Sketch and label all angles and sides (do calculations if you need to) for each of the following:
1 – 2 – √3
1 – 1 – √2

Calculate all of the other parts of the following right triangles.
*1. a = 3 b = 4

*2. c = 13 a = 5

3. b = 15 c = 17

4. a = 7 b = 24

*5. c = 20 A = 36^o

Calculate all other parts of the following triangles.
*6. A = 120^o b = 26 c = 15

*7. a = 17.32 c = 20.00 A = 60.00^o

8. a = 3600 B = 39^o C = 82^o

*9. a = 12 b = 18 c = 24

What is a Pythagorean triplett?
