What is a scalene obtuse triangle?
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.
Can a scalene be obtuse?
A scalene triangle can be acute-angled or obtuse-angled or right-angled.
Is obtuse and scalene the same?
An obtuse angle is one that measures greater than 90 degrees. An acute angle is one that measures less than 90 degrees. A scalene triangle is one which have all three sides of a triangle of different lengths and all three angles of different measures.
Is scalene obtuse or acute?
An obtuse triangle may be isosceles or scalene. In an acute triangle, all angles are less than right angles? each one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.
Can an obtuse triangle be equilateral?
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.
Where is the scalene muscle?
The scalene muscles are located deep in relation to the sternocleidomastoid muscle, lateral to the cervical spine, connecting the vertebrae to the first two ribs. The deep fascia or prevertebral fascia envelop the scalene muscles.
How do you tell if a scalene triangle is obtuse or acute?
To determine whether the triangle is acute, right, or obtuse, add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
What does scalene acute look like?
It would be an acute scalene triangle if: All angles are less than 90 degrees. All sides are unequal.
What is a scalene equilateral?
Scalene Triangle Equilateral: “equal”-lateral (lateral means side) so they have all equal sides. Also iSOSceles has two equal “Sides” joined by an “Odd” side. Scalene: means “uneven” or “odd”, so no equal sides.
Are all the obtuse angled triangles are scalene?
An obtuse triangle is a triangle in which one of the interior angles is greater than 90°. An obtuse triangle can also be called an obtuse-angled triangle. In general, an obtuse triangle can be a scalene triangle or isosceles triangle but not an equilateral triangle.
How do you calculate scalene?
We can find the scalene triangle’s area when the length of its two sides and the included angle are given.
- When two sides b and c and included angle A is known, the area of the triangle is, Area = (1/2) bc × sin A.
- When sides a and c and included angle B is known, the area of the triangle is, Area = (1/2) ac × sin B.
