Equilateral Triangle | Definition, Properties & Measurements
An equilateral triangle has three equal sides and three equal angles. To remember this, think of the prefix "equi-" as equal and "-lateral" as sides , meaning all sides are equal. Since the ...
Equilateral vs. Equiangular Polygons | Definition & Shapes
An equilateral polygon, however, is composed of sides of the same length, while an equiangular polygon is composed of equal, or congruent, interior angles. Equilateral Polygon Definition.
Area of an Equilateral Triangle | Formula, Calculation & Examples
An equilateral triangle is a triangle with three equal sides. In an equilateral triangle, all of the angles will also be equal as well. Since there are {eq}180^\circ {/eq} in a triangle, the three ...
How to Inscribe an Equilateral Triangle in a Circle
Equilateral triangle: A triangle with equal side lengths. A geometric argument demonstrates that the three angles in an equilateral triangle are also equal in measure. Because the sum of angles in ...
Can a right triangle be equilateral? | Homework.Study.com
Equilateral Triangles: In geometry, an equilateral triangle is defined as a triangle that has all sides of equal length. Another property that all equilateral triangles satisfy is that the measure of their angles are all equal and have a measure of 60°. We can use this property to determine if a given triangle is equilateral or not.
How to divide an equilateral triangle into three equal parts
In an equilateral triangle ABC, the midpoints of the sides are labelled D, E and F. Prove that triangle DEF is an equilateral triangle. Two sides of an equilateral triangle are 3x +15 and x + 21. What could be the measure of the third side? Find the measure of each side of equilateral triangle RST with RS = 2x + 2, ST = 3x, and TR + 5x - 4.
Constructing an Equilateral Triangle | Geometry - Study.com
Equilateral triangle: An equilateral triangle is a three-sided shape in which all sides have the same length and all angles are the same (since a triangle's angles sum to {eq}180^{\circ}, {/eq ...
The Equilateral Triangle: - Homework.Study.com
The Equilateral Triangle: In geometry, a closed two-dimensional shape with three congruent sides is called an equilateral triangle. Since all the sides of an equilateral triangle are equal, all the inner angles of the triangle are also equal and measures {eq}\displaystyle{ 60^{\circ} }{/eq}.
How to Identify Scalene, Isosceles & Equilateral Triangles from ...
Equilateral Triangle: An equilateral triangle is a triangle whose three sides all have the same length, and all three angles have the same value of {eq}60^{\circ} {/eq}.
How to Classify Scalene, Isosceles & Equilateral Triangles by Side ...
Classifying Scalene, Isosceles, and Equilateral Triangles by Side Lengths. Step 1: Examine all side lengths. If each side length is different, the triangle is scalene. Otherwise, move to step 2.
