preimage
Let
f:A->B
f:A->B
be a map between sets
A
A
and
B
B
. Let
Y subset= B
Y subset= B
. Then the preimage of
Y
Y
under

f
is denoted by
f^(-1)(Y)

that map to elements in

under

vertical angles
Vertical Angles are when lines intersect.
So when you make a x the lines are vertical angles.

Adjacent Angles are when two lines are paral.
When the lines do not intersect.

reflex angles
A Reflex Angle is more than 180 degrees but less than 360 degrees.
Reflex Angle
Reflex Angle
This is a Reflex Angle
Well, the picture here shows a reflex angle. The angle is on the outside instead of the inside, making bigger that 180 degrees.
Layla B.
acute angles
An Acute Angle is less than 90 degrees.
external image angle54.gif
This angle is measured on the inside, and it is smaller than 90 degrees because its measured that way.
Layla B.
obtuse angles
An obtuse angle is an angle larger than 90 degrees, like the obtuse angle on the right.
