Types of Angles Math worksheet - Free Printable

The task is to identify the type of each angle shown in the image. Let's analyze each angle step by step:

Step 1: Understand the Types of Angles

There are several types of angles based on their measures:
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.

Step 2: Analyze Each Angle

#### Angle 1 (Top Left):
- The angle appears to be less than 90 degrees.
- Type: Acute Angle

#### Angle 2 (Top Right):
- The angle has a square symbol, which indicates it is exactly 90 degrees.
- Type: Right Angle

#### Angle 3 (Bottom Left):
- The angle appears to be more than 90 degrees but less than 180 degrees.
- Type: Obtuse Angle

#### Angle 4 (Bottom Right):
- The angle appears to be a straight line, indicating it is exactly 180 degrees.
- Type: Straight Angle

Step 3: Write Down the Answers

Now, we can fill in the blanks with the correct names for each angle:

1. Acute Angle
2. Right Angle
3. Obtuse Angle
4. Straight Angle

Final Answer:

\[
\boxed{\text{Acute Angle, Right Angle, Obtuse Angle, Straight Angle}}
\]
