Yes, if you are willing to go beyond standard plane geometry. For example, a triangle can have two right angles in addition to a third angle on the surface of a sphere. No, if you must stick to regular secondary school plane geometry.
No because the 3 angles of a triangle must add up to 180 degrees no less and no more
If there were less than two acute angles, there would be two (or more angles that were 90 degrees or more. Then the sum of the three angles of the triangle would be more than 180 degrees. But this is not possible because the interior angles of a triangle sum to 180 degrees.
Acute Angles: Less 90 degrees but more than 0 degrees. Obtuse Angles: More than 90 degrees but less than 180 degrees.
A triangle is acute if it is less than 90 degrees. It is obtuse if more than 90 degrees
an angle less than 90 degrees but more than 0 degrees.So basically, a triangle 89-1 degrees is an acute triangle.
If all three angles are less than 90 degrees, then it is called an Acute Triangle. If two angles are less than 90 degrees and the other one is 90 degrees, then it is called a Right Triangle. If one angle is more than 90 degrees and the other two are less than 90 degrees, then it is called an Obtuse Triangle. Hope this helps!
Because the 3 interior angles of a triangle add up to 180 degrees no more and no less but a right angle plus an obtuse angle would be over 180 degrees.
The 3 interior angles of a triangle add up to 180 degrees no more and no less
An acute triangle has no angle of 90 degrees or more. A right triangle has one angle of 90 degrees; the other two are less than 90 degrees. An obtuse triangle has one angle between 90° and 180°; the other two are less than 90°.
No because the 3 interior angles of a triangle add up to 180 degrees no more and no less but 2 obtuse angles plus another angle would have a sum of well over 180 degrees.
An impossibility because the 3 angles of a triangle must add up to 180 degrees no more and no less whereas two obtuse angles on their own would be greater than 180 degrees.
Neither. An acute triangle has all angles less than 90 degrees. An obtuse triangle has one angle more than 90 degrees. A right triangle is simply just a right triangle, since it has one angle of 90 degrees.
