Let's review some terms and rules that you might
see on your standardized test.
An angle or line that is bisected has
been cut in half.
A right angle has a degree measurement
of 90°. It is formed whenever two lines are perpendicular.
The symbol for perpendicular lines is ? .
Lines are parallel if they lie in the
same plane and never intersect, no matter how far they are extended.
If two lines are parallel, and one of the two
is perpendicular to a third line, then both lines are perpendicular to
the third line.
A straight line that intersects two parallel
lines is known as a transversal. Since a transversal intersects
both parallel lines at the same angle, the angles formed mirror
each other.
In the figure above, a° = e°, d° = h°,
b° = f°, and c° = g°.
