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 need at least two acute angles

No the answer is no people think about it a triangles sides all have to sum up to be 180 degrees.

Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.Yes. Two obtuse angles, of equal measure.

No an abtuse triangle can not have two obtuse 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.

no think about it

no, it is impossible

No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.

Obtuse

All triangles need at least two acute angles

Spherical triangles as on the earth's surface.

Similarities between these and all triangles are:They all have 3 sides and 3 angles. The sum of the three angles adds up to 180Â°.An acute angle is less than 90 degrees. An acute triangle has all three sides are acute.An obtuse angle is more than 90 degrees. An obtuse triangle has one angle which is obtuse, and because of the 180Â° rule above, the other two angles will be acute.So all triangles will have at least two acute angles.

No. All angles in a triangle must add up to 180 degrees. An obtuse angle is over 90 degrees. So, two obtuse angles would put you at 182 degrees, minimum.

If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.

An obtuse angle is greater than 90° (and less than 180° ) The other two angles therefore total less than 90° and so both must be acute angles.
