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).

RIGHT ANGLES

This picture is a

picture of a right

angle. A right

angle is an angle

that adds up to

90 degrees.

OBTUSE

ANGLESBelow 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.

To the left is

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.

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

To the right is a

supplementary

angle. This

means that

these two

angles add up to

180 degrees.

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.

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.

To the left is

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.
