'Equi' sort of means 'equal', and 'angular' obviously refers to angles, so the word means that all the angles are equal. In an equilateral triangle, we know that all the interior angles are the same..
Also to know is, what is the angle in an equilateral triangle?
Internal angle (degrees) 60° In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
Also Know, how do you describe a triangle? A triangle has three sides, three vertices, and three angles. The sum of the three interior angles of a triangle is always 180°. The sum of the length of two sides of a triangle is always greater than the length of the third side. A triangle with vertices P, Q, and R is denoted as ?PQR.
Regarding this, how do you describe an equilateral triangle?
A triangle which has all three of its sides equal in length. An equilateral triangle is one in which all three sides are congruent (same length). Because it also has the property that all three interior angles are equal, it really the same thing as an equiangular triangle.
How do you name an angle in a triangle?
- Equilateral triangle. The Equilateral triangle shown on the left has three congruent sides and three congruent angles.
- Isosceles triangle. The Isosceles triangle shown on the left has two equal sides and two equal angles.
- Scalene Triangle. The Scalene Triangle has no congruent sides.
- Acute Triangle.
- Obtuse Triangle.

Triangle. A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.What is the definition of scalene triangle?
Scalene Triangle. A scalene triangle is a triangle that has three unequal sides, such as those illustrated above. SEE ALSO: Acute Triangle, Equilateral Triangle, Isosceles Triangle, Obtuse Triangle, Triangle. CITE THIS AS: Weisstein, Eric W. "What are the properties of 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.What is unique about an equilateral triangle?
An equilateral triangle is a triangle with all three sides of equal length , corresponding to what could also be known as a "regular" triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal. An equilateral triangle also has three equal.What are the triangle types?
There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene.Is a right equilateral triangle possible?
An equilateral triangle can not be a right triangle. This makes sense because the angle measures in any triangle, not only an equilateral triangle, equal 180 degrees. In a right triangle, however, the 3 angles can NOT be congruent. This is because in a right triangle, one angle equals 90 degrees.What are the 7 types of 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.What is the centroid of equilateral triangle?
In an equilateral triangle the centroid is the same as. the point where the bisectors of the three angles meet which is termed as the incentre, the point where the three perpendicular bisectors of the sides meet which is termed as the circumcentre.Are all equilateral triangles congruent?
When triangles are congruent, the corresponding sides are equal. Since two equilateral triangles can have sides of different lengths each to each, comparatively, the corresponding sides are not equal. Hence, equilateral triangles will be congruent only if a side of one triangle is equal to a side of the other.What does a scalene triangle look like?
A scalene triangle has three sides of different lengths. No congruent sides. Note: The angles in a scalene triangle are also of different measures. An isosceles triangle has two congruent sides.What makes a right triangle?
A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure).What is a triangle example?
noun. The definition of a triangle is a shape with three angles and three sides. An example of something in the shape of a triangle is a piece of pizza.How do you determine the height of a triangle?
If you know the base and area of the triangle, you can divide the base by 2, then divide that by the area to find the height. To find the height of an equilateral triangle, use the Pythagorean Theorem, a^2 + b^2 = c^2.What is a triangle in a simple?
Triangle. A triangle is a shape, or a part of two dimensional space. It has three straight sides and three vertices. The three angles of a triangle always add up to 180° (180 degrees). It is the polygon with the least possible number of sides.What is a common triangle?
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form a simple ratio, such as 45-45-90.
