If two parallel planes are cut by a third plane,
then the lines of intersection are parallel
alternate interior angles
two nonadjacent interior angles on opposite sides of the transversal
Same side angles
two interior angles on the same side of the transversal
corresponding angles
two angles in corresponding positions relative to the two lines
If two parallel lines are cut by a transversal,
then corresponding angles are congruent
If two parallel lines are cut by transversal,
then alternate interior angles are congruent
If two parallel lines are cut by a transversal,
then same side interior angles are supplementary
If a transversal is perpendicular to one of two parallel lines,
then it is perpendicular to the other one also
If two parallel lines are cut by a transversal,
then correspondung angles are congruent
If two lines are cuy by a transversal and corresponding angles are congruent,
then the lines are parallel
If two lines are cuy by a transversal and alternate interioir angles are congruent,
then the lines are parallel
If two lines are cut by a transversal and same side interior angles are supplementary,
then the lines are parallel
In a plane two lines perpendicular to the same line
are parallel

there is exactly one line parallel to the given line
Through a point outside a line,
there is exactly on eline perpendicular to the given line
Two lines parallel to a third line
are parallel to each other
Scalene
no sides congruent
isosceles
at least two sides congruent
acute
three acute angles
obtuse
one obtuse angle
right
one right angle
equiangular
all angles congruent
The sum of the measure of the angles
of a triangle is 180
If two angles of one triangle are congruent to two angles of another triangle,
the the thrid angles are congruent
The acute angles of a right triangle
are complementary
The measure of an exterior angles of a triangle equals
the sum of measures of the two remote interioir angles
The sum of the meausre of angles or a convex polygon with n sides
is (n-2)180.
