Can there be more than 1 obtuse angle in a triangle?
Explanation: The sum of all the inner angles of a triangle must be exactly 180 degrees. An obtuse angle is more than 90 degrees, say 90+ɛ , meaning “something more than 90 .
How many angles does obtuse angle have?
Obtuse angle is one of the types of angles that form on the plane surface. In Geometry, an obtuse angle is an angle that is greater than 90° and less than 180°….Obtuse Angle.

What shape can have 2 obtuse angles?
There are a few shapes that have 2 acute angles and 2 obtuse angles, including the rhombus, parallelogram and trapezoid. These shapes differ from one another based on their number of congruent sides and number of parallel lines.
Can a triangle have two obtuse angles Why?
No, because if the triangle have two obtuse angles i.e., more than 90° angle, then the sum of all three angles of a triangle will not be equal to 180°.
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 angles does a pentagon have?
5 obtuse angles
Since, an obtuse angle is greater than 900 but smaller than 1800 . So, this means that 1080 must be an obtuse angle. Since, here there are a total five 1080 angles in the pentagon, so we can say that there are five obtuse angles in a regular pentagon. Hence, there are total 5 obtuse angles in a regular pentagon.
Can Quadrilaterals have 4 obtuse angles?
A quadrilateral cannot have four obtuse angles. An obtuse angle is one which measures greater than 90 degrees and less than 180 degrees.
What shapes have obtuse angles?
The following plane shapes or polygons have at least one obtuse angle in them. (A) Obtuse triangle, (B) rhombus, (C) trapezoid, (D) pentagon, (E) hexagon, and (F) heptagon. A plane shape or polygon may be regular or irregular.
Can a triangle have all angles equal to 60?
No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°.
How many obtuse angles does a trapezoid have?
2 obtuse angles
Explanation: A trapezoid can have 2 obtuse angles at most, because a trapezoid has two pairs of supplementary angles. Both supplementary angles cannot be obtuse at the same time.
Can a triangle have exactly one acute angle?
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°. So, every triangle needs to have at least 2 acute angles.
Can you have triangle with two acute angles?
A triangle can have two acute angles. Some examples of triangle types that have two acute angles are a right triangle and an isosceles right triangle.
Does every triangle have at least one obtuse angle?
Therefore, a triangle can never have more than one obtuse angle. When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg).
Is it possible for Triangle to have two right angles?
A triangle cannot have two right angles. The sum of all three internal angles of a triangle is always 180 degrees. If two angles of a traingle measured 90 degrees each, the third angle would have to measure 0 degrees. If the third angle was 0 degrees, it is not a triangle anymore.
