The sum of the angles in a triangle is 180°
All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180°
If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle.
If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle.
If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle.
If there is at most one right angle or an obtuse angle, there must be at least two acute angles.

Do all triangles have an acute angle?
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
What is a triangle with at least 2 acute angles?
All triangles have at least two acute angles so the question does not add any further value.
Do scalene triangles have acute angles?
Yes. Any triangle (in the standard Euclidian geometry) has at least 2 angles; some have 3.
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
What flag has 4 right triangles 2 equilateral triangles and 2 acute angles?
Possibly Great Britains
Do all triangles have an acute angle?

Do all triangles have two acute angles?
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.
What is a triangle with at least 2 acute angles?
All triangles have at least two acute angles so the question does not add any further value.
Are all triangles have 2 acute angles?
Yes, that is the least amount of acute angles a triangle may posses, but a triangle may also have three acute angles. The sum of all triangles' interior angles are equal to 180 degrees; therefore, it is physically impossible to have less than two acute angles, yet entirely possible to contain two or three acute angles.
Do scalene triangles have acute angles?
Yes. Any triangle (in the standard Euclidian geometry) has at least 2 angles; some have 3.
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
Is it true that all triangles have at least 2 acute angles?
Yes. The total degrees of the 3 angles in a triangle must equal 180, so it's not possible to have a triangle with 2 angles >= 90.
Can scalene triangles be acute or obtuse?
A scalene triangle can have 1 obtuse angle and 2 different acute angles or it can have 3 different acute angles providing that the 3 angles in both scalene triangles add up to 180 degrees.
Can a triangle have 2 acute angles?
yesss, because in an equilateral triangle all the angles are 60 degrees!! Most triangles have acute angles! :) xx
What flag has 4 right triangles 2 equilateral triangles and 2 acute angles?
Possibly Great Britains
Do acute triangels have right angels?
No because only right angle triangles have 2 acute angles
What are the least number of acute angles that a triangle can have?
It must have at least 2. We can prove this by contradiction. If there is one or less acute angle, there must be two or more angles of 90 degrees or more. This adds to over 180 degrees. Since triangles can only have a total of 180 degrees, this violates the definition of a triantle, so there must be at least two acute angles.
