In pair of complementary angles can at least one of them be an obtuse angle?

No, because complementary angles are two angles whose sum is 90 degrees.
An obtuse angle is greater than 90 degrees and less than 180 degrees.

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
Do triangles have at least 2 acute angles?
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
Does a kite have an obtuse angle?
Yes, a kite typically has at least one obtuse angle. A kite is a quadrilateral with two distinct pairs of consecutive, congruent sides. In a kite, the angles between the non-congruent sides (the angles opposite the longer and shorter sides) are usually not congruent. One of these angles can be obtuse, depending on the specific shape of the kite. However, it's important to note that a kite can also have acute angles, but it must have at least one obtuse angle.
What is a parallelogram that has at least one obtuse angle?
Any parallelogram that is not a rectangle or a square must have two obtuse angles (and two acute ones).
Do triangles have at least one right angle?
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
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
Can a trapezoid have one obtuse angle?
Trapezoids ALWAYS have at least one obtuse angle (if they have two right angles, then there will only be one obtuse angle), usually two (in any other circumstance, they will have two obtuse and two acute angles).
Does a trapezoid always have an obtuse angle?
Yes, because the angles have to add up to 360º, at least one angle has to be obtuse.
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
Do trapezoid have obtuse angles?
No but their 4 interior angles add up to 360 degrees
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.
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 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.
Do triangles have at least 2 acute angles?
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
What shape has 6 obtuse angles?
A hexagon has six angles. A regular hexagon has six angles and each one is equal in measure to 120 degrees. 120 degrees is an obtuse angle. Any regular polygon with at least 6 sides has at least 6 obtuse angles.
Does a dodecagon have obtuse angles?
Yes. Any polygon with more than four sides MUST have at least one obtuse angle.
What is a parallelogram that has at least one obtuse angle?
Any parallelogram that is not a rectangle or a square must have two obtuse angles (and two acute ones).
