I'm not sure I understand your actual question, but what you are actually asking with the wording is false. Two 30 degree angles would both be acute angles whos sum would only create another acute angle of 60 degrees. But if you have 2 acute angles, then the third would have to be obtuse to form a triangle.
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
an isocelesANS2:Any triangle that has one right angle will have 2 acute angles. An acute angle is less than 90 degrees and the sum of all angles in a triangle is 180 degrees. The sum of the other two angles would have to add to 90 degrees so they would both have to be less than 90 degrees.
An line that is not perpindicular to the other line makes an acute or obtuse angle Oblique lines are not parallel or perpendicular which would be lines that form acute or obtuse angles at the point of intersection.
It impossible for a triangle to have three acute angles. * * * * * What? A triangle most certainly can have three acute angles. Such a triangle would be called an acute-angled triangle!
Sides aren't acute, angles are. A triangle with three acute angles would be called (appropriately enough) an acute triangle.
The sum of two acute angles is sometimes an obtuse angle because, acute angles can measure from 10 to 90 degrees. Two 30 degree angles would both be acute whose sum would only create another acute angle of 60 degrees. But, two80 degree angles would both be acute angle whose sum would only create an obtuse angle.

It could, but that's not required. It can have either two or three acute angles.
no. all angles would be acute
noA 4th angle would have to be obtuse, because the acute angles could not sustain a quadrilateral.
No. By definition, an acute triangle is a triangle where all three angles are <90 degrees. Therefore, an equilateral triangle, where all the angles are 60 degrees would qualify as an acute triangle.
In any right triangle, the two angles at either end of the hypotenuse are both always acute angles. But I don't think that would be called an 'acute' triangle, because an acute triangle is one in which all three angles are acute ones.
Not true because supplementary angles add up to 180 degrees and two acute angles would be less than 180 degrees.
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.
First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
