Show Answer Key & Explanations Step-by-step solution for: Measuring Angles Worksheet | 4th Grade Geometry
It looks like you've uploaded a worksheet titled "Measuring Reflex Angles", which contains six diagrams of angles, and the task is to measure each reflex angle.

However, since I can't view or access images directly, I cannot see the actual diagrams or angles in your image. But I can help you solve this type of problem if you describe the angles or provide details about them.

What Are Reflex Angles?


A reflex angle is an angle that is greater than 180° but less than 360°. To measure a reflex angle:

1. First, measure the acute or obtuse angle formed by the two rays (this is the smaller angle).
2. Then subtract that measurement from 360° to get the reflex angle.

For example:
- If the smaller angle is 60°, the reflex angle is 360° − 60° = 300°.
- If the smaller angle is 120°, the reflex angle is 360° − 120° = 240°.

How to Solve Each Problem on the Worksheet



Each box has a diagram with two rays forming an angle. Here’s how to approach it:

#### Step-by-step Instructions:
1. Identify the smaller angle between the two rays using a protractor.
2. Subtract that value from 360° to find the reflex angle.
3. Write the answer in the "Angle:" line.

> ⚠️ Note: The angle shown might not be the reflex one — you need to determine whether the angle being asked for is the larger one (reflex) or the smaller one. Since the title says “Measuring Reflex Angles,” you’re likely supposed to give the larger angle.

Example (Hypothetical):


Suppose in one diagram, the two rays form a small angle of 75°.
Then the reflex angle is:
360° − 75° = 285°

So you would write: 285°

Please Help Me Help You!


To solve your specific worksheet, please describe the angles in each diagram — for example:
- In Box 1: The angle opens to the right, and the smaller angle appears to be about 45°.
- In Box 2: The angle opens upward, and the smaller angle looks like 120°.

Or, if you can, copy and paste the descriptions of the angles (e.g., "a large angle opening clockwise", etc.).

Once I have that, I’ll walk you through measuring each reflex angle step by step!
