Geometry: Constructing Perpendicular Lines

What is the primary characteristic of a perpendicular line?

• It is parallel to another line.

• It forms a 90-degree angle with another line.

• It never intersects with another line.

• It forms a 45-degree angle with another line.

Why is a different method needed to construct a perpendicular line through point B?

• Point B is outside the line.

• Point B is already perpendicular.

• Point B is not in the middle of the line.

• Point B is at the end of the line.

What tool is used to draw arcs when constructing a perpendicular line?

• Set square

• Compass

• Ruler

• Protractor

What is the purpose of marking the point of intersection when constructing a perpendicular line?

• To check the length of the line

• To identify the midpoint

• To measure the angle

• To align the ruler for drawing the line
