Therefore, .
Answer:
First, we must have a compass and a rule.
Step-by-step explanation:
1º) Place the tip of the compass in the vertex of the angle and draw a circumference that cuts the two straight lines that form the angle.
2º) Now place the compass at each point of intersection of the circumference of 1º with each line, drawing a circumference of equal radius at each point.
3º) Now we take the point of intersection of the circumferences of equal radius and center in each line that we assemble in point 2, and we join them to the vertex.
4º) In this way we draw the bisecting line to the angle formed by lines 0B and 0A as line 0P.
Have a nice day!
