In geometry, an equilateral triangle is a triangle that has all its sides equal in length. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure. Therefore, it is also called an equiangular triangle , where each angle measure 60 degrees. Just like other types of triangles , an equilateral triangle also has its area, perimeter and height formula. Let us learn more in this article.

Regular triangle definition

In geometry, an equilateral triangle is a triangle whose all three sides are of equal length. The sides of an equilateral triangle are congruent, which means that all sides are of equal length. All the interior angles are equal 60 degrees too. So, a triangle with equal sides is known as an equilateral triangle. The traces of triangles can be found all over the world, especially in construction. The ancient Egyptians were fond of them. The faces of the famous Pyramids of Egypt are triangular. The pyramids of Giza are the most famous pyramids built by the Egyptians in the second century B. Egyptians thought that the triangular shape of the pyramid symbolized the seat of their Sun God, Ra, on earth. What will be the perimeter of an equilateral triangle, assuming that all its sides are 30 inches in length? You know that the perimeter of an equilateral triangle is 3 times the side length. What will be the perimeter and semi perimeter of an equilateral triangle whose side measurement is 10 units? You know the perimeter of an equilateral triangle is 3 times the side length, and the semi-perimeter is half the perimeter. What do we mean by equilateral? So if a shape has all the sides of the same length it is called equilateral.

A triangle that has all its sides equal in dimension and each angle measure up to 60 degrees, is called an equilateral triangle. Play Play.

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 angles. The altitude of an equilateral triangle is. The inradius , circumradius , and area can be computed directly from the formulas for a general regular polygon with side length and sides,. The areas of the incircle and circumcircle are.

A triangle is a 3-sided polygon sometimes but not very commonly called the trigon. Every triangle has three sides and three angles, some of which may be the same. 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. All triangles are convex and bicentric. That portion of the plane enclosed by the triangle is called the triangle interior , while the remainder is the exterior.

Regular triangle definition

A triangle is a polygon with three corners and three sides, one of the basic shapes in geometry. The corners, also called vertices , are zero- dimensional points while the sides connecting them, also called edges , are one-dimensional line segments. The triangle's interior is a two-dimensional region. Sometimes an arbitrary edge is chosen to be the base , in which case the opposite vertex is called the apex. In Euclidean geometry , any two points determine a unique line segment situated within a unique straight line , and any three points, when non- collinear , determine a unique triangle situated within a unique flat plane. More generally, several points in Euclidean space of arbitrary dimension determine a simplex. In non-Euclidean geometries three straight segments also determine a triangle, for instance a spherical triangle or hyperbolic triangle. A geodesic triangle is a region of a general two-dimensional surface enclosed by three sides which are straight relative to the surface. A curvilinear triangle is a shape with three curved sides, for instance a circular triangle with circular-arc sides.

Combined Standard Deviation. The triangle of largest area of all those inscribed in a given circle is equilateral, and the triangle of smallest area of all those circumscribed around a given circle is also equilateral. Many of these quantities have simple relationships to the altitude "h" of each vertex from the opposite side:. S2CID MR The area of an equilateral triangle can be found by using the formula of the area of an equilateral triangle. The smallest equilateral triangle which can be inscribed in a unit square left figure has side length and area. In the case of the equilateral triangle, the perimeter will be the sum of all three sides. Methods for Euclidean Geometry. The formulas to find the area of an equilateral triangle and the perimeter of an equilateral triangle are mentioned below. Identify Triangles and Squares Game. Like And Unlike Algebraic Terms. Identify Triangles and Rectangles Game. The sides of an equilateral triangle are congruent, which means that all sides are of equal length.

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.

All triangles have 3 sides only. The equilateral triangle is considered as a regular polygon or a regular triangle as angles are equal and sides are also equal. The altitude of an equilateral triangle is. Did not receive OTP? If they are of equal lengths, then the triangle is equilateral. Article Talk. Greenwood Press. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal. The perimeter of an equilateral triangle is the sum of all its three equal sides. Start Quiz. Types Of Polygon. Identify Triangles and Rectangles Game. So, a triangle with equal sides is known as an equilateral triangle. Your Mobile number and Email id will not be published. Repeat with the other side of the line.
