How do you calculate obtuse?
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.
What is the sum of an obtuse angle?
The sum of the interior angles of the obtuse triangle is equal to 180 degrees only. This means the angle sum property for any triangle remains the same. Thus, if one angle is obtuse or more than 90 degrees, then the other two angles are definitely acute or both the angles are less than 90 degrees.
Which triangle is obtuse?
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.
What is the formula of acute angle?

What do you call the angle whose measure is 30?
Acute Angle: An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles. In the adjoining figure, ∠X0Y represents an acute angle.
What is an example of an obtuse angle?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc.
What are the examples of obtuse angle?
Examples of Obtuse Angles We know that angles measuring greater than 90° and less than 180° are called obtuse angles. Therefore, angles that measure 145°,150°,178°,149°, 91° are considered as obtuse angle examples.
What is 45degree angle?
What is a 45-Degree Angle? A 45-degree angle is exactly half of a 90-degree angle formed between two rays. It is an acute angle and two angles measuring 45 degrees from a right angle or a 90-degree angle. We know that an angle is formed when two rays meet at a vertex.
What are the properties of obtuse triangle?
Here are the properties of obtuse triangles:
- The longest side of the triangle is the side opposite to the obtuse angle.
- A triangle cannot have more than one obtuse angle.
- The sum of the other two angles in an obtuse triangle is always smaller than 90°.
How to find the value of an obtuse angle?
Find the value of x for the given triangle ABC. We know that the sum of the interior angles of a triangle is 180 degrees. ∠A + ∠B + ∠C = 180° ….. (1) ∠B = 96°. Thus, the value of x is 96°, which is an obtuse angle. If the reflex angle of the given rays is 244°, then what will be the measure of the interior angle?
What is the sum of the angles of 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. This means the angle sum property for any triangle remains the same.
When does an obtuse triangle have more than 90 degrees?
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.
Which is larger an acute angle or an obtuse angle?
An obtuse angle is larger than a right angle (measures 90º) and an acute angle (measures less than 90º), but it is smaller than a straight angle (180º). In other words, if we order the angles from least to greatest measurement it would be acute< right< obtuse < straight.
