Do triangles have at least two obtuse angles?
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
What is the generalization for a obtuse triangle quadrilateral and pentagon?
Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.
What do the triangles look like and what are the names?
Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles
Can a triangle can have two obtuse angles?
Yes, as long as there is at least one right angle in the triangle. No way.
What triangle is never acute of obtuse?
No triangle is never acute in the sense that every triangle has at least two acute angles.
What triangle has at least one obtuse angle?
-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.
What angles does a obtuse triangle need so it could be a obtuse triangle?
It needs at least 1 obtuse angle. Usually you can only have one obtuse angle, so the rest would be acute.
Do triangles have at least two obtuse angles?
No. A triangle can have only one obtuse angle. A triangle must have at least two acute angles
What has at least one obtuse angle?
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
What polygon has at least one obtuse angle?
An obtuse triangle has 1 obtuse angle and 2 different acute angles and they all add up to 180 degrees
What is the generalization for a obtuse triangle quadrilateral and pentagon?
Not sure what the question means. A triangle or quadrilateral may but need not contain an obtuse angle. A pentagon or any polygon with more sides must contain at least one obtuse angle.
Why can you not have two obtuse angles in a triangle?
-- The sum of all three angles inside every triangle is always 180 degrees. -- An obtuse angle is an angle with more than 90 degrees in it. -- So two obtuse angles have more than 180 degrees between them. -- So they can't both be in the same triangle, unless at least part of one of them is left hanging out.

Does a obtuse triangle have at least 2 equal sides?
obtuse triangle
What kind of angles does a triangle have in it acute or obtuse?
Every triangle must have at least two acute angles. The third one can be acute, right (90 degrees), or obtuse.
