What is the sum of the angles in a euclidean triangle?
180 degrees or pi radians.
Polygon with least number of sides?
In Euclidean 3-space: a triangle (3 sides)
Triangle with two 60 degree angles?
equilateral triangle (and so, if it is in Euclidean (plane) space, it has 3 angles all of which are 60°) otherwise (in Hyperbolic or Spherical space) it is an isosceles triangle.
To what do the internal angles of a triangle add?
In Euclidean geometry, 180. Other answers are possible, depending on the surface on which the triangle is drawn.
Can the median of an equilateral triangle be longer than its altitude?
For the equilateral triangle in Euclidean space(i.e, the triangles you see in general) median is the same as its altitude. So, both are of equal length.
Can a triangle be coplanar?
In Euclidean plane geometry every triangle MUST BE coplanar.
Can an obtuse angled triangle be an equilateral triangle?
No way. Never. At least not in Euclidean geometry.
What is the sum of the angles in a euclidean triangle?
180 degrees or pi radians.
What is the triangle angle sum theorem?
The sum of the interior angles of a triangle in euclidean geometry equal 180 degrees
Can a triangle be drawn with exactly one acute angle?
No, not in plane (Euclidean) geometry.
What do you call a triangle with two obtuse sides?
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
Polygon with least number of sides?
In Euclidean 3-space: a triangle (3 sides)
What is the sum of the interior angles of a triangle in non-Euclidean geometry?
Any number you like.
What is the sumof the measure of the three anglesin a triangle?
The sum of the three angles in any triangle is 180 degrees. In plane Euclidean geometry
What triangle has 2 acute angles?
In Euclidean geometry a right angle triangle has two acute angles. All others have three.
Is it true that an obtuse triangle can have a right angle?
In Euclidean geometry, a triangle must be one of these: acute, obtuse, or right. Maybe there is a non-Euclideangeometry for which some obtuse triangles can contain a right angle, but it doesn't happen in Euclidean geometry.
Can a triangle have two right angles yes or no?
No. A triangle's angles must add up to 180 degrees so it cannot have two right angles. However, the answer is yes if you are talking about a triangle on the surface of a sphere. In this case the geometry is non-Euclidean. If you are staying with standard Euclidean geometry, then the answer no above is correct.
