How do you name a triangle with side lengths?

How do you name a triangle with side lengths?

There are three possibilities when looking at the three sides of a triangle.

1. No sides are the same length, called a “Scalene Triangle”
2. Two sides are the same length, called an “Isosceles Triangle”.
3. Three sides are the same length, called an “Equilateral Triangle”.

How do you classify a triangle by its sides?

When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.

What are two ways to name a triangle?

1. (a) REF.Image. ⇒ Acute triangle. → as every angle less than 90∘ ⇒ Isosceles triangle. → as Two sides and Two angles same.
2. (b) REF.Image. ⇒ Right angle triangle. → as one angle is 90∘ ⇒ Scalene triangle. → as all sides of different length.
3. (c) REF.Image. ⇒ Obtuse triangle. → as one angle is more than 90∘ ⇒ Isosceles triangle.

Are all sides of a triangle the same length?

All of the sides in an equilateral triangle are the same lengths.

Are the sides a triangle?

A triangle has three sides, three angles, and three vertices. The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle. The sum of the length of any two sides of a triangle is greater than the length of the third side.

Is a triangle in which all three sides have the same length?

A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.

What is the special name for this type of triangle?

There are three special names given to triangles that tell how many sides (or angles) are equal.

What is the name of a triangle with 3 different sides?

Scalene. A scalene triangle has three different angles and none of its sides are equal in length.

What are the types of triangles and their definitions?

Triangles are shapes with three sides. There are different names for the types of triangles. A triangle’s type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene. The green lines mark the sides of equal (the same) length.

How would you describe a triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted △ A B C {\\displaystyle \riangle ABC} .

What are the names of the sides of a triangle?

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. All triangles are convex and bicentric.

What are the angles of a triangle?

The triangle is a two-dimensional shape with three inside angles. These inside angles are said to be interior angles of the triangle and it will sum up to 180 degrees. These inside angles are classified into three types: Angle 1+angle 2+ angles 3= 180 degrees.
