Step-by-step explanation:
Let EF and GH are the two lines segment of length a and b such that a> b
We can construct line AB by using ruler and compasses.
- Step 1: Draw a line longer than the combined length of EF + GH or (a+b) and mark a point A on it
- Step 2: Using a compass, cut a line segment AC on line l equal to the length of EF by keeping its metal point of A
- Step 3: Using a compass, cut a line segment BC on line l equal to the length of EF by keeping its metal point of B
- Step 4: Using a compass, cut a line segment AH online AC equal to haft of the length of AC
=> we have a line segment with length equal to (EF+GH)/ 2
Hope it will find you well.
