Your answer is, Acute triangle
<u>Acute Triangles</u>
An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
In order for you to tell whether a triangle is acute. you have to look at all the angle points given in the triangle and if the triangle equals less then 90 that means it is acute.
Thus,<u> an acute triangle </u>is your answer.
