Answer:
1. Right angle triangle, 2. One triangle, 3. No triangle
Step-by-step explanation:
1. Has a 90-degree angle which makes it a right-angle triangle.
2. 30 + 60 + 90 = 180 degrees. Hence it satisfies the angle sum property so it is a triangle, a right-angle triangle.
3. It does not form a triangle as it does not satisfy the triangle inequality property, which is the sum of the two smaller sides should be greater than the larger side. 2 + 4 = 6, which is smaller than 7.
