Constructing Bisectors and Locating Points

What is the first step in constructing a perpendicular bisector?

• Set the compass to less than halfway.

• Draw a straight line through the midpoint.

• Create arcs only above the line segment.

• Set the compass to over halfway.

How do you bisect an angle using a compass?

• Create arcs from the vertex of the angle.

• Draw a straight line from one side of the angle.

• Use a ruler to measure the angle.

• Create arcs within the angle from each side.

What shape is formed by the locus of points around a single point?

• A circle

• A rectangle

• A triangle

• A square

What is the locus of points between two lines?

• An angle bisector

• A perpendicular bisector

• A tangent

• A parallel line

In the context of loci, what does it mean for a region to be closer to one point than another?

• It is within the region defined by the angle bisector.

• It is equidistant from both points.

• It is within a circle around the point.

• It is on the perpendicular bisector.
