Question
Decide if you want to make an obtuse,acute, or right angle and select three angle measures. Don't use 50,60,or 70 as the three measurements. How is the Triangle Angle Sum Theorem important for creating triangles? How many triangles can you make with three angle measurements? Draw one or more ( if possible) examples.

### Angle Selection
Let's create an acute angle triangle by selecting three angle measures that are all less than 90 degrees and that add up to 180 degrees:
- 30 degrees
- 60 degrees
- 90 degrees
### Importance of the Triangle Angle Sum Theorem
The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees. This theorem is crucial for creating triangles because:
1. **Validation**: When you select three angle measures, you can verify whether they can form a triangle by checking if their sum is 180 degrees.
2. **Uniqueness**: Knowing that the angles must add up to 180 degrees ensures that there are specific proportions and corresponds to the existence of unique triangles with those angles.
### Number of Triangles with Three Angle Measurements
With three specific angle measurements, you can determine the type of triangle that can be formed:
- **Unique Triangles**: For any set of acute angles that sums to 180 degrees, corresponding triangles can be formed, but they'll all be similar triangles.
- **Certain Combinations**: For example, the combination of 30°, 60°, and 90° only allows for one unique triangle shape (the triangle is similar regardless of size).
### Example Triangle
Let's visualize a triangle with the chosen angles:
```
B
/\
/ \
/ \
A------C
```
- Angle A = 30°
- Angle B = 60°
- Angle C = 90°
### Drawing
Here's a representation of a triangle with the specified angles.

In conclusion, with the set of angles of 30°, 60°, and 90°, we can create one unique right triangle, while variations in size can occur, but the characteristics will remain consistent due to the angles.
