Triangles - Equilateral, Isosceles and Scalene - Math is Fun
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
Equilateral triangle - Wikipedia
An equilateral triangle is a triangle in which all three sides have the same length, and all three angles are equal. Because of these properties, the equilateral triangle is a regular polygon , occasionally known as the regular triangle .
Equilateral Triangle - Definition, Properties, Formulas & Examples …
An equilateral triangle is a triangle with all three equal sides and each angle measures up to 60 degrees. Learn formulas of area, perimeter and height of an equilateral triangle at BYJU'S with examples.
Isosceles triangle - Wikipedia
In geometry, an isosceles triangle (/ aɪ ˈ s ɒ s ə l iː z /) is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case .
Isosceles triangle - Math.net
An isosceles triangle is a triangle that has at least two sides of equal length. Since the sides of a triangle correspond to its angles, this means that isosceles triangles also have two angles of equal measure.
Equilateral Triangle - Formula, Properties, Definition, Examples
Equilateral triangle is a triangle in which all sides are equal and angles are also equal. The value of each angle of an equilateral triangle is 60 degrees. Learn more about the equilateral triangle, properties, formulas along with solved examples.
Isosceles Triangle -- from Wolfram MathWorld
2024年11月26日 · An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal.
Triangle Types and Classifications: Isosceles, Equilateral, Obtuse ...
The Isosceles triangle shown on the left has two equal sides and two equal angles.
Equilateral Triangle - Definition, Properties, Example, Fact
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.
Equilateral Triangle - Definition, Examples, Formulas
2024年10月4日 · An equilateral triangle, also known as a triangle with equal sides, is a fundamental shape in geometry. Each of its sides is of equal length, and its interior angles are all 60 degrees, making it a 60-degree triangle. This perfect balance of equal sides and angles qualifies the equilateral triangle
