Follow the instructions and try drawing your own constructions using a pencil, ruler, a compass and some paper. Also get to know how loci and three figure bearings can help us in our daily lives.

What are perpendicular lines?

Lines that go in the same direction but the distance between them remains the same

Two lines drawn at right angles to each other

A line drawn to cut another line or angle in half

What is a bisector?

What is 'the path of a point that moves according to a certain rule'?

Locus

Midpoint

Bisector

Which mathematical apparatus, in addition to a pencil and ruler, is needed to find the midpoint of a line segment?

Calculator

Compass

Protractor

How many arcs do you need to draw when constructing a perpendicular to a line through a point on the line or above it?

What is the minimum number of arcs needed to construct an angle bisector correctly?

What is the locus of a point that's from a fixed point?

Circle

Disk with a hole in the middle

Square

What is the locus of a point that's further than from a fixed point and less than from the same point?

What does this construction represent?
