# Construction of trapezoid

Construct a trapezoid if b = 4cm, c = 7cm, d = 4,5cm, v = 3 cm (Procedure, discussion, sketch, analysis, construction)

Correct result:

n =  7

#### Solution:

$1.CD ; |CD|=c=7 \ \\ 2.k_{1} ; k_{1}(C;r=b=4 \ cm) \ \\ 3.k_{2} ; k_{2}(D;r=d=4.5 \ cm) \ \\ 4. p ; p || CD; v(p,CD)=v=3 \ cm \ \\ 5. A=p \cap k_{2} \ \\ 6. B=p \cap k_{1} \ \\ 7. ABCD \ \\ \ \\ n=7$
