Answer:
Acute triangle
Explanation:
A triangle with two angles measuring 40 degrees and 70 degrees is not a unique triangle because the sum of the angles in any triangle is always 180 degrees.
However, we can say that this triangle is an acute triangle because all of its angles measure less than 90 degrees. We could also say that it is a scalene triangle because all three of its sides have different lengths.
To uniquely identify a triangle, we need to know either the length of its sides or the length of at least one side and the measures of at least two angles.
