What is an equilateral in math?

What is an equilateral in math?

A shape is equilateral if all the sides are the same length. In geometry class, people learn about many shapes, such as triangles and squares. A square is equilateral, because all of its sides are the same length. A rhombus is also equilateral — its sides are also the same length.

What is an example of an equilateral?

In geometry, an equilateral triangle is a triangle that has all its sides equal in length. For example, a triangle with its three sides equal to 5cm is an equilateral triangle. Since the three sides are equal therefore the three angles, opposite to the equal sides, are equal in measure.

What means equilateral triangle?

mathematics. : a triangle in which all three sides are the same length.

What is equilateral area?

In an equilateral triangle, median, angle bisector and altitude for all sides are all the same and are the lines of symmetry of the equilateral triangle. The area of an equilateral triangle is √3 a2/ 4. The perimeter of an equilateral triangle is 3a.

What is a sentence for equilateral?

(1) Use your protractor to construct an equilateral triangle. (2) Its outline roughly forms an equilateral triangle. (3) The angles are equal, for ABC is equilateral. (4) The regular hexagon comprises six radial equilateral triangles.

What does equiangular mean in geometry?

angles are equal
The term equiangular indicates that, in some figures, the angles are equal. It can be used to describe polygons, such as an equiangular pentagon. The fact that the angles of a figure are congruent does not automatically mean that the sides are.

What is difference between equilateral and equiangular?

An equiangular polygon is a polygon in which all angles are equal. An equilateral polygon is a polygon with equal sides. If both sides and angles are equal then the polygon is called regular.

Are all equilateral equiangular?

Every equilateral triangle is also an isosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too. Hence, every equilateral triangle is also equiangular.

What is equilateral triangle Class 7?

Equilateral Triangle: A triangle in which all three sides are of equal length and three angles are equal. Each angle is 60°

What is isosceles shape?

In geometry, an isosceles triangle 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.

What is area of quadrilateral?

Area of the quadrilateral is the region enclosed by the four sides of this polygon. The general formula of the area of a quadrilateral is base * height, also written as b*h and the unit of measurement is m2.

What is the formula of area of equilateral?

You can use the Pythagorean theorem and height of the right triangles within the equilateral to determine the missing side lengths of an equilateral triangle. Then, you can use the formula A = √3/4 (a²) to determine the area of an equilateral triangle.

What is the root word of equilateral?

The first two are of Greek (and related) origins; the word “equilateral” is of Latin origin: scalene (adjective): from the Indo-European root skel- “to cut.” Greek skalenos originally meant “stirred up, hoed up.”

What is the definition of equilateral in math?

equilateral – a figure whose sides are all equal figure – a combination of points and lines and planes that form a visible palpable shape equal – having the same quantity, value, or measure as another; “on equal terms”; “all men are equal before the law”

What does equiangular and equilateral mean?

Equilateral means having all the sides equal.[1] Equiangular means having all the angles equal.[2] A regular polygon[3] is a polygon[4] that is both equiangular and equilateral. A triangle that is equilateral must also be equiangular. Conversely, a triangle that is equiangular must also be equilateral.

What is equilateral and irregular?

An equilateral triangle is a regular triangle with 60° internal angles . Thus if the number of sides n is odd, a tangential polygon is equilateral if and only if it is regular. An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure.
