ACUTE ANGLES
To the left is a
picture of an
acute angle. An
acute angle is an
angle that is less
than 90 degrees,
(or a right
angle).
3.
RIGHT ANGLES
Thispicture is a
picture of a right
angle. A right
angle is an angle
that adds up to
90 degrees.
4.
OBTUSE
ANGLES
Below is a picture of an obtuse angle. An obtuse
angle is an angle that is larger than a right angle;
where the lines extend out farther than if they
were straight.
5.
To the left is
STRAIGHT ANGLES
a straight
angle, and
that is when
the right
angle moves
its lines
downward to
create two
straight lines
on either
sides of the
points.
6.
COMPLEMENTARY ANGLES
To the right is a
picture of a
complementary angle.
A complementary
angle is two angles
whose measures both
have a sum of 90
degrees. There are a
couple ways in which
you could create a
complementary angle
with these images on
the right.

SUPPLEMENTARY ANGLES
Tothe right is a
supplementary
angle. This
means that
these two
angles add up to
180 degrees.
8.
BISECTED ANGLES
Pictured above is a bisected angle. A bisect
angle is an angle that divides something into
two equal parts, so that its spilt halfway
down the middle.
9.
VERTICAL ANGLES
To the right is a
vertical angle. A
vertical angle is an
angle with two
nonadjacent angles
formed by 2
intersecting lines.
Also, all vertical
angles are congruent.
10.
To the left is
LINEAR ANGLES
a linear
angle. A
linear pair
is a pair of
adjacent
angles
whose
noncommon
sides are
opposite
rays. The
angles in a
linear pair
also have a
measure
that add up
to 180
degrees.
