Based on your description of the steps being taken, it appears that you are performing a construction related to either bisectors or lines through a certain point. However, without the specific images or a description of the steps involved, it's challenging to determine the exact type of construction.
If the steps involve creating angles that are equal and dividing an angle into two equal parts, then the construction is likely for an angle bisector.
If the steps involve dividing a line segment into two equal parts or creating a line that is perpendicular to a given segment, then you are performing a perpendicular bisector construction.
If you are creating lines that meet at a right angle, then it involves perpendicular lines.
If the construction involves drawing a pair of parallel lines through a point that is not located on a given line, then it is for parallel lines through a point not on the given line.
Please analyze the steps or consider any specific details in the construction to determine the correct response. If you can share more about what each step entails, I can help you pinpoint the specific type of construction accurately.
