Sometimes it is if its 3 interior angles are acute angles and add up to 180 degrees
two
An isosceles triange has 2 equal sides and 2 equal interior angles whereas an acute triangle has 3 unequal sides and 3 interior acute angles of different sizes
180 degrees no matter if it is regular, obtuse, acute, right, etc. Was this helpful?
If you meen the three angles, all tirangles angles add to 180 degrees. But all of the angles must be different, that's what makes it an acute triange. So three.
Depends on the exact measurements. If, for example, the two acute angles are ten and twelve, the remaining angle would be one hundred fifty-eight, which is obtuse. But if the acute angles are thirty and eighty-nine, then the remaining angle would be sixty-one, which is also acute.
A triangle can be an equilateral triangle, an isosceles triangle, a scalene triangle, a right triangle, an acute triange, or an obtuse triangle.See related link below for more info on triangles

never.
Yes
width x highest point on the triange then divide by 2 if equilateral/isoceles triange height x width then divide by 2 if right angled triange/scalene triangle
a cone
three
