Can there be 2 obtuse angles in a triangle?
The answer is “No”. Reason: If a triangle has two obtuse angles, then the sum of all the 3 interior angles will not be equal to 180 degrees.
What shape has exactly 2 obtuse angles?
trapezoid Here is an example of a trapezoid. Notice that this trapezoid has two acute angles and two obtuse angles.

What is the sum of 2 obtuse angles?
Reflex angle is one that measures between 180° and 360°. So, suppose we have two obtuse angles of measure 100° and 105° then their sum 205° lies between 180° and 360° and ∴ is a reflex angle.
Can a triangle have 2 acute angles?
(iii) A triangle cannot have two acute angles.
What is a triangle with 2 acute angles?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
Does a rhombus have 2 obtuse angles?
∴ there are two acute angles (one in each pair) and two obtuse angles (one in each pair) present in a rhombus.
Does a parallelogram have 2 obtuse angles?
Thus, consecutive angles are supplementary and the opposite angles are equal. So, from the figure, we can see that there are only two obtuse angles (i.e. ∠ A & ∠ C) of a parallelogram which are equal and the other two angles are acute angles. Hence, we can say that a parallelogram has two Obtuse Angles.
How many obtuse angles are in a triangle?
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…
Does a right triangle always have 2 acute angles?
A right triangle can, and must, have exactly two acute angles. To see this, just remember that the sum of the angles of a triangle must be 180∘ . As a right triangle has one angle equal to 90∘ , this means the sum of the remaining two angles must be 180∘−90∘=90∘ .
Is an isosceles triangle obtuse?
An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90 degrees and 180 degrees) and the other two acute angles are equal in measurement….Isosceles Obtuse Triangle.

How many obtuse angles Can a triangle have?
one obtuse angle 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.
Does a trapezoid have 2 obtuse angles?
A trapezoid can have 2 obtuse angles at most.
Does a trapezoid have obtuse angles?
Trapezoid ABCD has two pairs of supplementary angles. Then Both supplementary angles cannot be obtuse at the same time. Hence A trapezoid can have two obtuse angles at most. So, the correct answer is “2”.
Can you have a triangle with two acute angles?
(iii) A triangle cannot have two acute angles.
What is obtuse triangle?
An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn't be a triangle.) A triangle must be either obtuse, acute, or right.
How many obtuse angles can a right triangle have?
A right triangle can have no obtuse angles.
Can an isosceles triangle have 2 obtuse angles?
Answer and Explanation: An isosceles triangle can have only one obtuse angle. In fact, any triangle can have at most one obtuse angle. An obtuse angle is an angle greater than 0∘ and less than 180∘ .
What triangle can be obtuse?
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°.
What is a triangle with 2 equal angles?
An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg).
How many obtuse angles are possible in a triangle?
one obtuse angle 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.
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°.
Are all scalene triangles obtuse?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
Can an isosceles triangle be obtuse?
Types of Triangles by Length In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below).
What does a obtuse scalene triangle look like?
Obtuse Scalene Triangle Definition In geometry, an obtuse scalene triangle can be defined as a triangle whose one of the angles measures greater than 90 degrees but less than 180 degrees and the other two angles are less than 90 degrees. All three sides and angles are different in measurement.
What is an obtuse angle triangle?
A triangle whose any one of the angles is an obtuse angle or more than 90°, then it is called an obtuse-angled triangle or obtuse triangle. The sum of the interior angles of the obtuse triangle is equal to 180° only.
Can isosceles be obtuse?
An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90 degrees and 180 degrees) and the other two acute angles are equal in measurement. One example of isosceles obtuse triangle angles is 30°, 30°, and 120°.
Can a scalene triangle be obtuse?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
What is an obtuse isosceles triangle?
An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90 degrees and 180 degrees) and the other two acute angles are equal in measurement. One example of isosceles obtuse triangle angles is 30°, 30°, and 120°.
Can an equilateral triangle be obtuse?
An equilateral triangle can never be obtuse. Since an equilateral triangle has equal sides and angles, each angle measures 60°, which is acute. Therefore, an equilateral angle can never be obtuse-angled. A triangle cannot be right-angled and obtuse-angled at the same time.
