The sum of all three angles is 180 degrees.
If there are not two acute angle then there are two (or more) angles that are 90 degrees or more. So those two angles sum to 180 degrees of more and so the third angle must have a negative measure - and that is not possible.

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.
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.
What are triangles according to angle?
All triangles have 3 interior angles that add up to 180 degrees and they are:- Right angle triangle: 90 degree angle and 2 acute angles Obtuse triangle: An obtuse angle and 2 acute angles Scalene triangle: 3 acute angles of different sizes Isosceles triangle: 2 equal angles and another angle Equilateral triangle: 3 equal angles that each measures 60 degrees
Can right triangle and acute triangles be similar?
No because a right ange triangle has a 90 degree angle and 2 acute angles whereas an acute triangle has 3 acute angles all of which are less than 90 degrees
What is the difference between an acute triangle and a scalene triangle?
scalene triangles can be the same as acute triangles beacause scalene triangles are triangles with 3 different angles and sides. An acote triangle needs to have 3 angles less than 90 degrees.
Which shapes have acute angles?
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have 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.
A triangle with 2 acute angles?
All right angle triangles have 2 acute angles and one 90 degree angle.
What types of triangles have at least two acute angles?
All triangles need at least two acute angles
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
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
What is the relationship between isosceles and acute triangles?
They are both triangles. And both have acute angles
What is the least number of angles an acute triangle can have?
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
Do acute triangels have right angels?
No because only right angle triangles have 2 acute angles
