To solve the problem of identifying the types of angles in the given worksheet, we need to classify each angle as
acute,
obtuse,
straight, or
right. Here's a step-by-step explanation:
Definitions:
1.
Acute Angle: An angle that measures less than 90 degrees.
2.
Right Angle: An angle that measures exactly 90 degrees.
3.
Obtuse Angle: An angle that measures more than 90 degrees but less than 180 degrees.
4.
Straight Angle: An angle that measures exactly 180 degrees.
Solution:
Let's analyze each angle one by one:
#### 1)
- The angle is less than 90 degrees.
-
Classification: Acute
#### 2)
- The angle forms a straight line.
-
Classification: Straight
#### 3)
- The angle is more than 90 degrees but less than 180 degrees.
-
Classification: Obtuse
#### 4)
- The angle is less than 90 degrees.
-
Classification: Acute
#### 5)
- The angle forms a perfect square corner.
-
Classification: Right
#### 6)
- The angle is less than 90 degrees.
-
Classification: Acute
#### 7)
- The angle is more than 90 degrees but less than 180 degrees.
-
Classification: Obtuse
#### 8)
- The angle forms a perfect square corner.
-
Classification: Right
#### 9)
- The angle is less than 90 degrees.
-
Classification: Acute
#### 10)
- The angle is more than 90 degrees but less than 180 degrees.
-
Classification: Obtuse
#### 11)
- The angle forms a straight line.
-
Classification: Straight
#### 12)
- The angle forms a perfect square corner.
-
Classification: Right
Final Answer:
\[
\boxed{
\begin{array}{ccc}
1) & \text{Acute} & 2) & \text{Straight} & 3) & \text{Obtuse} \\
4) & \text{Acute} & 5) & \text{Right} & 6) & \text{Acute} \\
7) & \text{Obtuse} & 8) & \text{Right} & 9) & \text{Acute} \\
10) & \text{Obtuse} & 11) & \text{Straight} & 12) & \text{Right} \\
\end{array}
}
\]
