Use Axioms, Proposition 1,
Mauney’s Postulate, and
Congruence Theorems SAS and SSS
to bisect a given line segment. Also,
construct a line perpendicular to a
given line segment.
How do we define a right
angle, today?
According to Euclid, what is a
right angle?
Why did Euclid define right
angle in such a strange way?
When a straight line standing on a
straight line makes the adjacent angles
equal to one another, each of the equal
angles is right, and the straight line
standing on the other is called a
perpendicular to that on which it
stands.
