Can a scalene triangle be acute?

YES. An ACUTE triangle contains threeacute angles. (In other words, each angle of an acutetriangle is less than 90 degrees.) A SCALENE triangle isone in which all sides have different lengths (and therefore, allangles have different measures).

.

Considering this, can a triangle be scalene and Equiangular?

Answer and Explanation: An equiangular triangle cannot bescalene. By definition, a scalene triangle is atriangle in which each side of the triangle has adifferent length.

Also, what angles does a scalene triangle have? Like other triangles, all the anglesinside a scalene triangle add up to 180 degrees. And justlike all the sides of a scalene triangle have differentlengths, all the angles of a scalene triangle havedifferent measures.

Beside this, what is a scalene triangle?

A scalene triangle is a triangle that hasthree unequal sides, such as those illustrated above. SEE ALSO:Acute Triangle, Equilateral Triangle, IsoscelesTriangle, Obtuse Triangle,Triangle.

How do you know if a triangle is a scalene?

A triangle is scalene if all of its three sidesare different (in which case, the three angles are also different).If two of its sides are equal, a triangle is calledisosceles. A triangle with all three equal sides is calledequilateral.

Related Question Answers

Is an obtuse equilateral triangle possible?

You are right - an equilateral triangle cannothave an obtuse angle. An equilateral triangle has allthree sides the same, therefore all three angles are the same. Whenyou add up the angles of any triangle, you get 180 degrees,so 180 divided by 3 is 60 - the size of every angle of anyequilateral triangle.

Can an isosceles triangle be an equilateral triangle?

An isosceles triangle is one with two equalsides. Therefore, every equilateral triangle isisosceles, but not every isosceles triangle isequilateral. Under that (uncommon) definition, anequilateral triangle, having three equal sides, would ofcourse not be isosceles.

What type of triangle can an isosceles triangle be?

Types of Triangle by Angle A right triangle may be isosceles orscalene. In an obtuse triangle, one angle is greater than aright angle—it is more than 90 degrees. An obtusetriangle may be isosceles or scalene. In an acutetriangle, all angles are less than right angles—eachone is less than 90 degrees.

Which is the best definition of a scalene triangle?

Answer: Which is the best definition of a scalenetriangle? A scalene triangle is a triangle withall the three unequal sides. None of its sides is equal to anyother. But like other triangles, all the angles inside ascalene triangle add up to 180 degrees.

What does obtuse triangle mean?

An obtuse triangle is a triangle in whichone of the angles is an obtuse angle. (Obviously, only asingle angle in a triangle can be obtuse or itwouldn't be a triangle.) A triangle must be eitherobtuse, acute, or right.

Are isosceles triangles always acute?

Answer and Explanation: No, isosceles triangles are not alwaysacute. An isosceles triangle has two of its sides andinternal angles being equal.

How many obtuse angles can an isosceles triangle have?

An obtuse triangle may be either isosceles(two equal sides and two equal angles) or scalene (no equalsides or angles). An obtuse triangle has only oneinscribed square.

What is the difference between equilateral triangle and isosceles triangle?

In an equilateral triangle , all the sides andangles are of equal length. In an isosceles triangle, 2 of the sides are equal and 2 angles areequal.

How do you find the area of an isosceles triangle?

To find the area of an isosceles triangle usingthe lengths of the sides, label the lengths of each side, the base,and the height if it's provided. Then, use the equation Area= ½ base times height to find the area.

Is a scalene triangle a polygon?

No, a scalene triangle is not a regularpolygon. All the triangles are polygons andare characterised by having three sides.

What are the 7 triangles?

There are a number of different types oftriangles, such as equilateral triangles, righttriangles, scalene triangles, obtusetriangles, acute triangles, and isoscelestriangles.

How many triangles are there?

Most people on Quora agreed that the answer is 24, witheach row containing six triangles. However, if you reallywant to get technical, the truly “correct” answer is25. The 25th triangle is hidden in the 'A' inthe artist's signature in the right-handcorner.

What are the angles in an isosceles triangle?

An isosceles triangle is a triangle with(at least) two equal sides. In the figure above, the two equalsides have length and the remaining side has length . This propertyis equivalent to two angles of the triangle beingequal. An isosceles triangle therefore has both two equalsides and two equal angles.

What is an acute isosceles triangle?

In geometry, an isosceles triangle is atriangle that has two sides of equal length. The two anglesopposite the legs are equal and are always acute, so theclassification of the triangle as acute, right, orobtuse depends only on the angle between its two legs.

What are the 6 types of triangles?

Triangle Types and Classifications: Isosceles,Equilateral, Obtuse, Acute and Scalene.

How do you name a triangle?

To name a triangle we often use itsvertices (the name of the endpoints). The trianglebelow is named ABC. A triangle has three angles. The sum ofthe measures of the angles is always 180° in atriangle.

Does the Pythagorean theorem Work on scalene triangles?

Note that the Pythagorean Theorem onlyworks with right triangles. You can use thePythagorean Theorem to find the length of the hypotenuse ofa right triangle if you know the length of thetriangle's other two sides, called the legs.

Does a triangle always have 3 acute angles?

In any triangle, two of the interiorangles are always acute (less than 90degrees)^*, so there are three possibilities forthe third angle: Less than 90° - all three anglesare acute and so the triangle is acute.Exactly 90° - it is a right triangle.

What is the properties of scalene triangle?

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