Measuring Angles with a Protractor - Worksheet | Maths Year 5 - Free Printable

Problem Analysis:

The worksheet involves measuring acute angles using a protractor and identifying the most likely angle measurements for given diagrams. Let's solve each part step by step.

Part 1: Measure the angles below

#### a)
- The red line starts at the 0° mark on the protractor.
- It extends to the 35° mark.
- Therefore, the angle is 35°.

#### b)
- The red line starts at the 0° mark on the protractor.
- It extends to the 90° mark.
- Therefore, the angle is 90° (though it is not acute, we will still measure it as requested).

#### c)
- The red line starts at the 0° mark on the protractor.
- It extends to the 45° mark.
- Therefore, the angle is 45°.

#### d)
- The red line starts at the 0° mark on the protractor.
- It extends to the 25° mark.
- Therefore, the angle is 25°.

#### e)
- The red line starts at the 0° mark on the protractor.
- It extends to the 60° mark.
- Therefore, the angle is 60°.

#### f)
- The red line starts at the 0° mark on the protractor.
- It extends to the 70° mark.
- Therefore, the angle is 70°.

Part 2: Circle the measurement that is the most likely for the angles below

#### a)
- The angle appears to be acute and less than 90°.
- Among the options: 130°, 30°, 90°, the most likely measurement is 30°.

#### b)
- The angle appears to be obtuse and greater than 90° but less than 180°.
- Among the options: 95°, 180°, 70°, the most likely measurement is 95°.

#### c)
- The angle appears to be obtuse and greater than 90° but less than 180°.
- Among the options: 85°, 250°, 110°, the most likely measurement is 110°.

Boxed Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{Part 1:} & \text{a) 35°, b) 90°, c) 45°, d) 25°, e) 60°, f) 70°} \\
\text{Part 2:} & \text{a) 30°, b) 95°, c) 110°}
\end{array}
}
