Equilateral Angle

Equilateral triangle - Wikipedia

Equilateral triangles are found in many other geometric constructs. The intersection of circles whose centers are a radius width apart is a pair of equilateral arches, each of which can be inscribed with an equilateral triangle.Triangles - Equilateral, Isosceles and Scalene

There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles: Equilateral Triangle . Three equal sides Three equal angles, always 60° Isosceles Triangle ... Has a right angle (90°) Obtuse Triangle . Has an angle more than 90°Properties of Equilateral Triangles | Brilliant Math ...

Because the equilateral triangle is, in some sense, the simplest polygon, many typically important properties are easily calculable. For instance, for an equilateral triangle with side length \(\color{red}{s}\), we have the following: The altitude, median, angle bisector, and perpendicular bisector for each side are all the same single line.Equilateral Triangles Calculator

calculatorsoup› Geometry› PlaneAn equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. The altitude shown h is hb or, the altitude of b. For equilateral triangles h = ha = hb = hc. If you have any 1 known you can find the other 4 unknowns.3 Ways to Draw an Equilateral Triangle - wikiHow

So this angle is going to be equal to that angle. And we showed all of this in the video where we proved the relationships between the sides of a 30-60-90 triangle. Well, in a regular equilateral triangle…Author: Sal KhanHow to Find X in an Equilateral Triangle | Sciencing

Remember that every angle on an equilateral triangle is 60 degrees. If x is one of the angles, the solution is 60 degrees. Use the given length of a different side of the triangle to determine the value of x if x is the length of one side.What is an Equilateral Triangle? - Definition, Properties ...

Since the sum of a triangle's angles is always 180 degrees, each angle in an equilateral triangle must measure 60 degrees. This is because we must divide 180 degrees evenly between the three ...Equilateral - math word definition - Math Open Reference

The area of an equilateral triangle can be calculated in the usual way, but in this special case of an equilateral triangle, it is also given by the formula: where S is the length of any one side. See Area of an equilateral triangle. With an equilateral triangle, the radius of the incircle is exactly half the radius of the circumcircle.Proofs concerning equilateral triangles (video) | Khan Academy

By the base angles theorem every equilateral triangle is also equiangular. By the triangle angle sum theorem the three angles add to 180°. By the substitution and division properties each of the angles are 60°. By the definition of an obtuse angle, none of the angles in an equilateral triangle are obtuse. QED.If one angle of a triangle is 60 degrees, is it equilateral?

For a triangle to be equilateral, all its angles must be 60° and consequently, all it sides must be equal. A right angled scalene triangle can have an angle 60°, with one 90° and a 30° angle. And to take it a step further, any triangle can have a 60° angle with the sum of …Triangles - InfoPlease
