How do you construct a perpendicular line through a point not on the line?

Back

1. Place the compass point on the given point and draw an arc that intersects the line at two points. 2. Without changing the compass width, draw arcs from each intersection point. 3. Draw a line through the intersection of the arcs.

What is the first step in constructing a perpendicular bisector?

Back

Place the compass point on one endpoint of the segment and draw an arc above and below the segment.

Front

What is the purpose of a compass in geometric constructions?

Back

A compass is used to draw arcs and circles, which are essential for various constructions.

What is the construction for creating an angle congruent to a given angle?

Back

1. Place the compass point on the vertex of the given angle and draw an arc. 2. Without changing the compass width, place the compass point on the vertex of the new angle and draw an arc. 3. Use the intersection points to create the congruent angle.

What is the significance of the intersection point in constructing perpendicular lines?

Back

The intersection point is where the two lines meet at a right angle, confirming they are perpendicular.
