Answer: One
Step-by-step explanation:
You can only draw one triangle with these angle measurements.
First, we will check to make sure they can create a triangle.
30° + 60°+ 90° = 180° ✓
Since we are given three angles, and one of them is a 90-degree angle making this triangle a right triangle, we can only create one unique triangle.
-> Any other triangles created from this angle will be the same triangle flipped or rotated.
