sorry about that.

yeah a,b,c are the sides.

is opposite of a

is opposite of b

is opposite of c

no law of sines nor cosine.

only use of basic things:

+

+

= 180º

*[a*2 +

*b*2 =

*c*2]

*a* +

*b* >

*c*
(a and b are catheti and c is hypotenuse)

+ all the facts about various triangles. (right, oblique,equilateral, isosceles, scalene)

the construction is supposed to be made without "calculating" anything, just the process of how to draw a triangle with the given info.

(no need to draw it, just need someone to explain the steps)..

what i'd do first is:

1) draw the b (=5cm)

2) measure gamma (=30º)

3) draw the line on which a will be.

4) ... < stuck here.
