Answer and Explanation: An equiangular triangle cannot be scalene. By definition, a scalene triangle is a triangle in which each side of the triangle has a different length..
Beside this, can a scalene triangle be equilateral?
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.
Similarly, which triangle is both scalene and right? A right triangle is scalene if all three sides are a different length such as one with sides of 3, 4 and 5. You can have an isosceles right triangle with two sides the same length such as a 1, 1 and 2 sided triangle. An equilateral right triangle (all three sides equal) is not possible.
Accordingly, can an isosceles triangle be Equiangular?
An equilateral triangle is always equiangular (see below). In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below). In a scalene triangle, none of the sides are the same length.
How do you prove a triangle is a scalene?
The converse of this is also true - If all three angles are different, then the triangle is scalene, and all the sides are different lengths.
- Interior angles are all different.
- Shortest side is opposite the smallest angle.
- Longest side is opposite the largest angle.
- Area of a scalene triangle.

What are the 7 triangles?
To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene. Geometry Sticks.What are the properties of a scalene triangle?
Properties of the scalene triangle: All angles of a scalene triangle are unequal. A scalene triangle has no line of symmetry. The angle opposite to the longest side would be the greatest angle and vice versa. All sides of the given scalene triangle are unequal.Is every equilateral triangle isosceles is every isosceles triangle equilateral?
An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral. Under that (uncommon) definition, an equilateral triangle, having three equal sides, would of course not be isosceles.What does equilateral triangle look like?
An equilateral triangle has three equal sides and three equal angles (which are each 60°). Its equal angles make it equiangular as well as equilateral.What are the three types of triangle?
What are the types of triangle? - The sum of angles in any triangle is 180°.
- An equilateral triangle has three equal sides and angles.
- An isosceles triangle can be drawn in many different ways.
- A right-angled triangle has one 90° angle.
- A scalene triangle has three different angles and none of its sides are equal in length.
What type of triangle can an isosceles triangle be?
An Isosceles triangle is a triangle with at lest two sides of the same length. A right triangle is a triangle with one right angle. It is possible to have an Isosceles-Right Triangle.How many acute angles can an isosceles triangle have?

Are isosceles triangles always right?
No, an isosceles triangle is not ALWAYS a right triangle. An Isosceles Triangle can be a right triangle, it is a 45–45–90 degree triangle. An isosceles triangle is a triangle with two sides of equal length.What does a obtuse isosceles triangle look like?
An isosceles triangle is a triangle that has at least two equal sides. So, for an isosceles triangle to be considered obtuse, it just has to be a triangle with two equal sides and an angle that is in between 90 degrees and 180 degrees.What does obtuse triangle mean?
An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.Can an acute triangle be isosceles?
An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. Note: It is possible for a right triangle to also be scalene or isosceles. An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle).What is the difference between isosceles triangle and equilateral triangle?
In an equilateral triangle , all the sides and angles are of equal length. In an isosceles triangle , 2 of the sides are equal and 2 angles are equal.How do you prove an isosceles triangle is equilateral?
From the Base Angles Theorem, the angles opposite congruent sides in an isosceles triangle are congruent. So, if all three sides of the triangle are congruent, then all of the angles are congruent or egin{align*}60^circend{align*} each. Equilateral Triangles Theorem: All equilateral triangles are also equiangular.What is equiangular triangle in math?
An equiangular triangle is a triangle where all three interior angles are equal in measure. Because the interior angles of any triangle always add up to 180°, each angle is always a third of that, or 60°Is a triangle a polygon?
As you learned in the last lesson, a triangle is the simplest polygon, having three sides and three angles. The sum of the three angles of a triangle is equal to 180 degrees. Triangles are classified by sides and by angles. Move your cursor over the triangles to learn more.Can a triangle have 3 right angles?
No, real, triangle can have three right angles. The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.Can a triangle have two obtuse angles?
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.What is a triangle with 3 equal sides?
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral.
