What is a triangle short answer?
In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
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 called a triangle?
A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle. The above shown shapes are triangles. The symbol of a triangle is ∆. A triangle is a polygon with three sides. Triangles can be classified on the basis of sides and angles.
What is triangle with example?
The definition of a triangle is a shape with three angles and three sides. An example of something in the shape of a triangle is a piece of pizza. (geometry) A polygon with three sides and three angles.
How many angles does have triangle?
three angles
The sum of the three angles of any triangle is equal to 180 degrees.
What is the error symbol?
ε: “Error term” in regression/statistics; more generally used to denote an arbitrarily small, positive number. ∈ (Variant Epsilon) This version of epsilon is used in set theory to mean “belongs to” or “is in the set of”: x ∈ X; similarly used to indicate the range of a parameter: x ∈ [0, 1].
What does a triangle look like?
An equilateral triangle is a 3-sided polygon (enclosed shape) that whose sides are all congruent (equal in length). An equilateral triangle also has 3 congruent angles, all 60˚ in measure. They look like this:
How do you identify a triangle?
Identifying isosceles triangles. An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. The two angles touching the base (which are congruent, or equal) are called base angles.
What are the rules of a triangle?
The triangle inequality rule, which states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.
What are the attributes of a triangle?
Triangles can be classified by 2 different attributes. A triangle may be named for its angles or for its lines. It may also be given a dual classification and classified by lines and angles. You will be able to give every triangle a more specific name after learning how to classify triangles.
