What shape has exactly 2 obtuse angles?
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.
Can a triangle have 2 obtuse exterior angles?
Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.
What is a triangle with 2 acute angles?
A triangle with a right angle and two acute angles is called right angled triangle.
Can an isosceles triangle have two obtuse angles?
Answer and Explanation: An isosceles triangle can have only one obtuse angle.
Does a rhombus have 2 obtuse angles?
The key here is to know that a rhombus has two pairs of congruent angles. In other words, the two acute angles of a rhombus are equal and the two obtuse angles are equal.
Does a triangle have obtuse angles?
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.
Which triangle is an obtuse triangle?
A triangle whose any one of the angles is an obtuse angle or more than 90 degrees, then it is called obtuse-angled triangle or obtuse triangle. The sum of the interior angles of the obtuse triangle is equal to 180 degrees only.
Is an isosceles triangle obtuse?
Since a triangle is obtuse or right if and only if one of its angles is obtuse or right, respectively, an isosceles triangle is obtuse, right or acute if and only if its apex angle is respectively obtuse, right or acute.
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°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees.
Is a scalene triangle obtuse?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
Does every triangle have at least one obtuse angle?
Two obtuse angles by definition mean that there would be two angles of (at least) 91 degrees each. 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.
Can a triangle be drawn with exactly one acute angle?
A triangle can be drawn with more than one acute angle. A triangle can be drawn with exactly one acute angle. A triangle can be drawn with exactly one obtuse angle. A triangle can be drawn with exaclty one right angle. Q. How many triangles exist with the given angle measures? 55°, 45°, 90°
What are the properties of an obtuse angle triangle?
Two angles are acute (less than 90 degrees) and one angle is obtuse (greater than 90 degrees but less than 180 degrees).
What triangle has one right angle and two acute angles?
sin (x) = opposite/hypothenuse
