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.
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 ...
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 ...
Sierpinski Triangle | Definition, Pattern & Formula - Study.com
All of this leads to a more precise definition of the Sierpinski Triangle: it is a self-similar fractal that results from removing the triangle connecting the three midpoints of an equilateral ...
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 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 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.
Are all squares and all rectangles equilateral?
The sum of the perimeters of an equilateral triangle and a square is 15. Find the dimensions of the triangle and the square that produce a minimum total area. The sum of the perimeters of an equilateral triangle and a square is 13. Find the dimensions of the triangle and the square that produce a minimum total area.
