Observations on
Definitions
in of Euclid
Euclid
27. Amongst right three sided figures that
is a right-angled triangle which has
a right angle.
No triangle that can be can
have more than one right angle &
this defines what seems to be intended by this
definition is that right angled triangles with
more than one are not inconsistent.
28. M as in Euclid
29. An acute angled triangle is
that all the angles of which are
necessarily acute. A triangle
A triangle may have its three
angles acute angles: but in a right
angled triangle & in a obtuse-angled
triangle two angles cannot but be
acute.
30 Amongst four-sided figures that is
a square whose sides are all equal
to one another & its angles are right
angles & equal to each other.
31. That is an oblong the angles of
which are right angles but the sides not
equal sided although the opposite
sides are equal.
32. That a rhombus the sides are
equal but not right angled & of each pair of angles
the two opposite are equal to each
other & in each pair Of the four angles of which it
is are contained in it two are equal
to one another but not to the
other pair.
