Constructing a line perpendicular to a given line and through a point not on the line is one of the most important constructions in geometry. This process is known as dropping a perpendicular, because ...

Equation of altitudes and perpendicular bisectors Now use the information you already have about finding the equation of a line and apply it to the dashed lines shown in these triangles.

Drag points A, B, and P to change the relationship between these points. Use the buttons, in order, to demonstrate how a line is constructed perpendicular to a given line and through a given point.

A line which cuts another line into two equal parts and meets it at a right angle is called a perpendicular close perpendicularPerpendicular lines are at 90° (right angles) to each other ...

The angle bisector is the line that divides the angle in half, and the perpendicular bisector is the line that goes through the midpoint of a side and is perpendicular to that side. After the teacher ...
