12
√13 is hypotenuse of right triangle
using a² + b² = c²
a² + b² = c²
c² = (√13)² = 13
find two square numbers whose addition is 13
13 = 4 + 9
= 2² + 3²
draw line segment of either 3 or 2 units
say 3 units
draw perpendicular to that segment as usual
draw arc of 2 units
join the points to get √13
2² + 3² = c²
4 + 9 = c²
c = √13
hope it helps you
