Classifying, Measuring, & Drawing Angles Worksheet | TPT - Free Printable

To solve the problem of measuring and classifying each angle as acute, right, or obtuse, we need to follow these steps:

Steps:

1. Measure Each Angle: Use a protractor to measure the size of each angle in degrees.
2. Classify Each Angle:
- Acute Angle: An angle that measures less than 90°.
- Right Angle: An angle that measures exactly 90°.
- Obtuse Angle: An angle that measures more than 90° but less than 180°.

Solution:

Let's go through each angle one by one:

#### Angle ①
- Measure: Using a protractor, measure the angle.
- Classification: If the angle is less than 90°, it is acute; if it is exactly 90°, it is right; if it is more than 90°, it is obtuse.

#### Angle ②
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ③
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ④
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ⑤
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ⑥
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ⑦
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

#### Angle ⑧
- Measure: Using a protractor, measure the angle.
- Classification: Same as above.

Example Measurements (Hypothetical):

Assume the following measurements for illustration purposes:
- ①: 45° → Acute
- ②: 120° → Obtuse
- ③: 90° → Right
- ④: 60° → Acute
- ⑤: 150° → Obtuse
- ⑥: 90° → Right
- ⑦: 30° → Acute
- ⑧: 100° → Obtuse

Final Answer:

Based on the hypothetical measurements:
- ①: Acute
- ②: Obtuse
- ③: Right
- ④: Acute
- ⑤: Obtuse
- ⑥: Right
- ⑦: Acute
- ⑧: Obtuse

$$
\boxed{
\text{①: Acute, ②: Obtuse, ③: Right, ④: Acute, ⑤: Obtuse, ⑥: Right, ⑦: Acute, ⑧: Obtuse}
}
$$

Note:

You need to physically measure each angle using a protractor to get the exact values. The classifications will depend on the actual measurements.
