- Properties of Equilateral Triangles - Brilliant
An equilateral triangle is a triangle whose three sides all have the same length They are the only regular polygon with three sides, and appear in a variety of contexts, in both basic geometry and more advanced topics such as complex number geometry and geometric inequalities
- Equilateral Triangle Formula: Meaning, Proofs, Examples - Toppr
An equilateral triangle is a triangle whose all three sides are having the same length This is the only regular polygon with three sides It appears in a variety of contexts, in both basic geometries as well as in many advanced topics Let us start learning about the equilateral triangle formula
- Equilateral and Isosceles Triangles - Toppr
Equilateral Triangles This is an Equilateral Triangle In equilateral triangles all the sides are equal So we can say that they have identical sides and identical angles No matter what is the length of the sides, angles in equilateral triangles have a measure of 60° each Since the sum of the angles in the triangle is 180°, therefore, each angle in the equilateral triangle must measure 60
- Area of Equilateral Triangle Formula - Toppr
In this topic, we will discover about equilateral triangles and its area The student will also learn the area of equilateral triangle formula An equilateral triangle is a triangle whose all three sides are having the same length This is the only regular polygon with three sides
- Complex Numbers in Geometry | Brilliant Math Science Wiki
In plane geometry, complex numbers can be used to represent points, and thus other geometric objects as well such as lines, circles, and polygons They are somewhat similar to Cartesian coordinates in the sense that they are used to algebraically prove geometric results, but they are especially useful in proving results involving circles and or regular polygons (unlike Cartesian coordinates
- Find the moment of inertia of a thin sheet of mass
Given: a thin sheet of mass M in the shape of an equilateral triangle The length of each side is L To find the moment of inertia about the vertex parallel to the base Solution: The area moment of inertial of a triangle about an axis passing through its centroid and parallel to one side is bh3 36
- Prove that the medians of an equilateral triangle are equal. - Toppr
Using the concept of slope, prove that medians of an equilateral triangle are perpendicular to the corresponding sides
- D, E, and F are, respectively the mid-points of sides BC, CA . . . - Toppr
Let ABC be the triangle and D, E and F be the mid-point of BC, CA and AB respectively We have to show triangle formed DEF is an equilateral triangle We know the line segment joining the mid-points of two sides of a triangle is half of the third side
