Content

All constructions begin with a point. A point occupies a position, but has no magnitude.

A point is named by a capital letter, A, P, Q, R, etc.

A line is the distance between two points. It may be a straight distance (for a straight line) or a curve. A line segment has both magnitude and direction and is denoted by PQ, between points P and Q.

Example 1

Construct a line PQ of length 4.7 cm.

Solution

Construct a line segment as…
