No. All triangles MUST have at least two acute angles.
All triangles need 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 have at least two acute angles. Acute triangles have three. Rhomboids also have two acute angles.

Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
All acute triangles have 3 interior angles and 3 exterior angles. This is true for all triangles.
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.
All triangles have at least two acute angles so the question does not add any further value.
Yes all equilateral triangles are acute triangles, but not all acute triangle are equilateral triangles.
