The video tutorial covers the construction of perpendicular and angle bisectors using a compass, and explains the concept of loci, which are sets of points satisfying specific conditions. It discusses how to construct bisectors and evaluate loci between points and lines, and how to identify regions based on these loci.

What is the first step in constructing a perpendicular bisector?

• Set the compass to over halfway of the line segment.

• Create arcs only above the line segment.

• Set the compass to less than halfway of the line segment.

• Draw a straight line through the midpoint.

When bisecting an angle, what should you do after marking off each line segment?

• Change the compass width.

• Create arcs outside the angle.

• Draw a circle around the angle.

• Create arcs within the angle from each side.

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

• A rectangle

• A circle

• A triangle

• A square

How is the locus of points between two points typically represented?

• As a triangle

• As a straight line

• As a perpendicular bisector

• As a circle

What is the locus of points between two lines known as?

• A perpendicular bisector

• A parallel line

• An angle bisector

• A tangent
