Does equilateral have equal sides?
Equilateral triangles have three equal sides and angles When all of a triangle's sides are of equal length and all of its angles have a measure of 60∘, it is considered equilateral. You could also say equiangular, since the three angle measures are all the same (60∘). The triangle below is an equilateral triangle.
Which is an equilateral triangle?
An equilateral triangle is a triangle with all three sides of equal length , corresponding to what could also be known as a "regular" triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides equal. An equilateral triangle also has three equal.
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 triangle has two sides?
A triangle with two sides of equal length is an isosceles triangle.
How do you find the sides of an equilateral triangle?
When the perimeter is given: Clearly the perimeter of an equilateral triangle is thrice the length of its side, dividing the perimeter by 3 would yield the length of the side of such a triangle. Hence the length of side of an equilateral triangle is one- third of the perimeter of the triangle.

Do all triangles have 3 sides?
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.
Does an equilateral triangle have 3 equal sides?
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
What is equilateral triangle class 9?
It has 3 equal sides. It has 3 equal angles. Since the sum of the interior angles is 180 degrees, every angle of an equilateral triangle is 60 degrees. It is a regular polygon with 3 sides.
What is the meaning of equilateral triangle?
: a triangle in which all three sides are the same length.
Do triangles have 3 or 4 sides?
A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. Every triangle has three sides and three angles, some of which may be the same.
What are the 3 sides of triangle?
In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles.
Does a triangle have to be equilateral?
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°….

Does a triangle have 3 sides?
Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.
Do triangles only have 3 sides?
That is, a triangle has three sides, and three terms describe triangles based on their sides; a triangle also has three angles, and three classifications of triangles are based on their angles.
What is an equilateral triangle Class 7?
An equilateral triangle is the one in which all the three sides are equal. It is a special case of the isosceles triangle where the third side is also equal. In the triangle ABC, AB = BC = CA. Properties of an equilateral triangle are: It has 3 equal sides.
Is a triangle 3 equal sides?
An equilateral triangle has three equal length sides and three equal inside angles. Each of the angles measures 60º.
Are there 4 sides in a triangle?
The triangle has three (3) sides. The triangle is a polygon that contains three sides and three inner angles and three vertices.
Can a triangle have 3 equal sides?
An equilateral triangle has three equal length sides and three equal inside angles.
What type of triangle has 3 sides?
Properties of the scalene triangle:
| All angles of a scalene triangle are unequal. | A scalene triangle has no line of symmetry. |
|---|---|
| All sides of the given scalene triangle are unequal. | The given triangle cannot be divided into two identical halves. There is no line of symmetry. |
How many equal sides does an isosceles triangle?
Legs: The two equal sides of an isosceles triangle are known as 'legs'. In the triangle ABC (given above), AB and AC are the two legs of the isosceles triangle. 2. Base: The 'base' of an isosceles triangle is the third and unequal side.
Does a triangle always have 3 equal sides?
Because an equilateral triangle is also isosceles, all triangles are either scalene or isosceles. But when people call a triangle isosceles, they're usually referring to a triangle with only two equal sides, because if the triangle had three equal sides, they'd call it equilateral.
How many equal sides does a obtuse triangle have?
An obtuse triangle may be either isosceles (two equal sides and two equal angles) or scalene (no equal sides or angles). An obtuse triangle has only one inscribed square.
How many sides does isosceles have?

What are the 7 types of triangle?
To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.
What is a triangle with 3 equal sides?
An equilateral triangle is one in which all three sides and angles are equal. So, B is correct.
What is S in triangle?
Another is Heron's formula which gives the area in terms of the three sides of the triangle, specifically, as the square root of the product s(s – a)(s – b)(s – c) where s is the semiperimeter of the triangle, that is, s = (a + b + c)/2.
