For this case we have to classify the triangles according to their angles as:
- Rectangular triangles: They have an angle of 90 degrees.
- Acutangles triangles: They have their three acute angles (less than 90 degrees)
- Obtuse triangles: They have an angle greater than 90 degrees.
Thus, the triangle described in the problem is an acutangle triangle.
Answer:
Acutangle triangle
