An obtuse triangle will have one and only one obtuse angle. The other two angles are acute angles.
Can an obtuse triangle be obtuse?
Obtuse Triangle Definition An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It’s impossible for a triangle to have more than one obtuse angle.
An angle is obtuse if its lies between 90 and 180 degrees. In this figure the interior angle of the triangle is two acute angles and an obtuse angle. So, the exterior angle is with two obtuse angles. Therefore, the triangle satisfies the above condition.
What triangle has 2 obtuse angles?
Answer and Explanation: No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.
What are the obtuse angles?
An obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees.
Does an obtuse triangle have 3 obtuse angles?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
How many obtuse angle are there?
Answer and Explanation: There can only be one obtuse angle in any triangle. This is because the measures of the interior angles of a triangle always must add up to 180…

Can a triangle be obtuse and scalene?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
Can two obtuse angles be supplementary?
Two obtuse angles can be supplementary angles.
Why can’t a triangle have two obtuse angles?
Give reason for your answer. No, because the sum of three angles of a triangle is 180 degree & sum of any two obtuse angles is always more than 180 degree. So, it can not be possible that a triangle have two obtuse angles.
Is an isosceles triangle an obtuse triangle?
What does it mean to be called obtuse?
Definition of obtuse 2a : lacking sharpness or quickness of sensibility or intellect : insensitive, stupid He is too obtuse to take a hint. b : difficult to comprehend : not clear or precise in thought or expression It is also, unfortunately, ill-written, and at times obtuse and often trivial.”
Which triangle has an obtuse angle?
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.
How many obtuse angles does a trapezoid have?
A trapezoid can have 2 obtuse angles at most.
How many obtuse angles are there in a right triangle?
A right triangle can have no obtuse angles. All the triangles follow the angle sum property and this property ensures that for any triangle, the…
How many obtuse angles are in an acute angle?
Answer and Explanation: There are exactly two acute angles in an obtuse triangle, where an acute angle is an angle with measure less than 90°. We can show why this is by…
Which shapes have at least 2 obtuse angles?
The trapezoid has 2 acute angles and 2 obtuse angles. It belongs in the group “acute and obtuse.” Remember to look at all of the angles in a shape before you put it in a group.
How do you know if its acute or obtuse?
Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
How do you find the angle of an obtuse triangle with two sides?
You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4.
Is the triangle obtuse acute or right?
How do you make a triangle obtuse?
Is Sohcahtoa only for right triangles?
Q: Is sohcahtoa only for right triangles? A: Yes, it only applies to right triangles. If we have an oblique triangle, then we can’t assume these trig ratios will work. We have other methods we’ll learn about in Math Analysis and Trigonometry such as the laws of sines and cosines to handle those cases.
What kind of triangle has one obtuse angle and two acute angles?
Explanation: An obtuse scalene triangle must have one obtuse interior angle and two acute angles. All triangles have three interior angles with a sum total of degrees.
Why does a triangle have 2 acute angles?
The definition of acute angle is that the range for the angle has to be 0∘
<α<90∘.>as the sum of those two angles becomes less than 180∘.
Can a triangle have two obtuse angles True or false?
The triangle cannot have two obtuse angles.
Can a triangle have all acute angles?
A triangle can never have only one acute angle. If a triangle has 1 acute angle, the other angles will be either right angles or obtuse angles which is not possible as the sum of interior angles of a triangle is always 180°.
Can a triangle be obtuse and equilateral?
The angles in an equilateral triangle are all 60 degrees. since all three angles are equal divide the total degrees in an triangle by 180 by 3. An obtuse angle is greater than 90 degrees. 60
< 90 so an equilateral triangle can not have an obtuse angle.
Is obtuse scalene possible?
Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles. Each angle has a measure of 60º. Note: All equiangular triangles are also equilateral.
Are obtuse angles supplementary?
No, two obtuse angles cannot form a supplementary angle. By the definition of obtuse angles, the angles that measure greater than 90° are obtuse. If you add two obtuse angles, the sum will be greater than 180°.
Can two obtuse angles be linear pair?
No, two obtuse angles cannot form a linear pair because their sum of angles is always greater than 180 degree.
Can a triangle have one obtuse and right angle?
No, a triangle cannot have an obtuse and a right angle.
Why is there only one obtuse angle in a triangle?
If there are 2 obtuse angles than the sum of the measure of 3 angles of triangle will be more than 180 degree. The property is the sum of the 3 angles of triangle is supplementary. So,only one obtuse angle must be in a triangle.
Which shape has acute and obtuse angles?
A trapezoid is a parallelogram with one pair of opposite sides parallel. Here is an example of a trapezoid. Notice that this trapezoid has two acute angles and two obtuse angles.
What is an example of obtuse?
The definition of obtuse is someone who is slow to understand things. An example of obtuse is someone who listens to a joke but doesn’t understand the punchline.
Can a quadrilateral have 4 obtuse angles?
