The ratios of sides of a 45-45-90 triangle are 1:1:√2
so you would multiply the length of one of the legs by √2 (which is not .5 !)
the ratios of sides of a 30-60-90 triangles are 1:√3:2
so, to find the length of the shorter leg of a 30-60-90 triangle, multiply the length of the longer leg by 1/√3
You should be able to answer the third part by yourself.
