All triangles need at least two acute angles
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
No. All triangles MUST have at least two acute angles.
Yes.
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
All triangles need at least two acute angles
All triangles have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.

No. All triangles MUST have at least two acute angles.
Yes.
All triangles have at least 2 acute angles. All 3 angles of a triangle will equal 180 degrees.
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.
Yes
All of them
Yes. In fact, all triangles MUST have at least two acute angles.
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
All triangles have at least two acute angles so the question does not add any further value.
