There are two set-squares in your box. What are the measures of the angles that are formed at their corners? Do they have any angle measure that is common?

Explanation

To solve the question, we need to find the measures of the angles formed at the corners of the two set-squares and check for any common angle measures.

### Step-by-Step Solution:

1. **Identify the Angles in the First Set-Square:**
- A typical set-square has three angles. For the first set-square, we measure the angles:
- Angle 1: 90 degrees
- Angle 2: 45 degrees
