2. Acute
This is an acute angle
The angle of this must be less than 90 degrees
3. Right Angel
This is a right angle
The angle must be equal to 90 degrees
4. Obtuse
This angle is obtuse
This means that the angle must measure
more than 90 degrees but less than 180
5. Straight Angle
This angle is straight
Straight angles must measure to 180 degrees
6. Complementary Angle
This is a complementary angle
This means that the two angles added
together will equal 90 degrees
7. Supplementary Angle
This is a supplementary angle
Supplementary angles have two parts that add
together to equal 180 degrees
8. Bisected Angle
This is a bisected angle
On these both parts of the angle must be
equivalent to each other
9. Vertical Angle
This is a vertical angle
This means that the two angles meet at
a certain point and the angles directly
across from each other must be equal
10. Linear Pair
This shows an example of a linear pair
A linear pair is two lines that intersect each
other and both sides add up to 180 degrees
