Vertical
Angles
Students should be able
to:
identify and describe the characteristics
of vertical angles
|
What
can you learn by looking at the letter X?
When
you look at the letter X, you see two pairs of VERTICAL
ANGLES, or angles opposite each other when two lines cross.
|
|
Vertical
angles are CONGRUENT. That means they are the same
size. |
In the X above, angle 1 is congruent
to angle 3, and angle 2 is congruent to angle 4. That means if
the measure of angle 1 is 95º, then the measure
of angle 3 is also 95º.
Angle 1 = Angle 3
&
Angle 2 = Angle 4
|
Vertical
angles share the same VERTEX, or the point where two lines INTERSECT,
or meet. |
|
Angles
that are not vertical in the X are SUPPLEMENTARY angles, or angles
with measurements that add up to 180º. |
