Perpendicular and Angle Bisector Calculator

FAQs

How do you find the perpendicular angle bisector? The perpendicular bisector of a line segment is a line that is both perpendicular to the segment and passes through its midpoint. To find the perpendicular bisector, follow these steps:

1. Determine Midpoint: Calculate the midpoint of the given line segment using the midpoint formula:
   Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2), where (x₁, y₁) and (x₂, y₂) are the coordinates of the endpoints.
2. Calculate Slope: Calculate the slope of the given line segment using the formula:
   Slope = (y₂ – y₁) / (x₂ – x₁).
3. Find Negative Reciprocal Slope: The negative reciprocal of the slope calculated in step 2 will give you the slope of the perpendicular bisector.
4. Use Point-Slope Form: Use the midpoint from step 1 and the slope from step 3 to write the equation of the perpendicular bisector using the point-slope form:
   y – y₁ = m * (x – x₁), where m is the slope from step 3.

How can you identify angle bisector and perpendicular bisector? An angle bisector is a line that divides an angle into two equal angles.
