Can a obtuse angle be scalene?

Can a obtuse angle be scalene?

It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. It may be acute, obtuse, equiangular, scalene, isosceles, or equilateral, but not a right triangle.

Is a scalene triangle an acute triangle?

An acute triangle is one whose all angles are acute (less than 90 degrees) and a scalene triangle is one whose all three sides and angles are different in measurement. So, the acute scalene triangle properties are listed below: It has three acute angles. All the sides and angles are different in measure.

How do you find an obtuse triangle?

To calculate the angle of an obtuse triangle, you need to square the lengths of the two sides of the triangle that will intersect to make the obtuse angle and add the squares of them. For example – if the two sides of the triangle are 2 and 4, then squaring them will give 4 and 16.

Is 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.

Is it acute right or obtuse?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

Is an obtuse triangle always acute?

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.

What shapes are 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.

Are scalene triangles equilateral?

Equilateral triangle has all three sides equal in length. Scalene triangle has all three sides of different length.

Are all sides congruent in a scalene triangle?

Scalene Triangle: The Scalene Triangle has no congruent sides. In other words, each side must have a different length. Scalene triangle-a triangle with no congruent sides. In the above triangle, all the sides of triangle denoted by a, b and c are unequal and angles x, y and z are also unequal.

Is a scalene triangle a regular or an irregular triangle?

Sometimes called an irregular triangle . Scalene triangles are triangles where each side is a different length. They are unusual in that the are defined by what they are not. Most triangles drawn at random would be scalene. The interior angles of a scalene triangle are always all different.

Is a scalene triangle always acute?

An equilateral triangle is always an acute triangle since the sum of the angles should be 180 degrees which when divided by 3 would equate to 60°. A scalene triangle is a right triangle. The correct answer would be option B. A scalene triangle is sometimes a right triangle. What is important is that the sides of the triangle are unequal.

What is the sum of the angles in a scalene triangle?

Scalene Triangle Definition. It is defined as, a triangle in which all the sides of a triangle are of different length and all the angles of a triangle are of different measures where the sum of the interior three angles of a triangle is always equal to 180 degrees.
