# Ruler and compass

Use a ruler and compass to construct a triangle ABC with AB 5cm BAC 60° and ACB 45°.

Result

a =  6.124 cm
b =  6.83 cm

#### Solution:

$a=6.124=\dfrac{ 1531 }{ 250 }=6.124 \ \text{cm}$

Try calculation via our triangle calculator.

$b=6.83=\dfrac{ 683 }{ 100 }=6.83 \ \text{cm}$
