Is a triangle the only shape with 3 sides?
The plural of "vertex" is "vertices" – a triangle has three vertices. The way we identify a polygon is usually by the number of sides it possesses, which is the same as its number of angles….Polygons in General.

What shape has 3 sides answer?
triangle The polygon with three sides is called a triangle. The word triangle explains itself, “tri-angle” means three angles.
What is a polygon with 3 sides called?
A 3-sided shape is called a triangle. Triangles are polygons with three sides, so any polygon with three sides is called a triangle.
What shape has 3 sides with different lengths?
triangle A triangle whose all three sides are of different lengths is called a scalene triangle.
What are three sides?
The polygon with three sides is called a triangle. The word triangle explains itself, “tri-angle” means three angles.
What shape is a rhombus?
In Euclidean geometry, a rhombus is a type of quadrilateral. It is a special case of a parallelogram, whose all sides are equal and diagonals intersect each other at 90 degrees. This is the basic property of rhombus. The shape of a rhombus is in a diamond shape.
What is a shape with 3 sides and 3 angles?
The triangle is one of the basic shapes in geometry. It is the simplest shape within a classification of shapes called polygons. All triangles have three sides and three angles, but they come in many different shapes and sizes.
Which of the following has three sides?
Triangle. A triangle is a closed figure made of three line segments. Every triangle has three sides, three angles, and three vertices.
What type of triangle has 3 sides the same length?
equilateral triangle An equilateral triangle has three equal length sides and three equal inside angles.
What are the 3 sides of a 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.
What shape is a trapezoid?
A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
What is trapezium shape?
A trapezium is a closed shape or a polygon, that has four sides, four corners/vertices and four angles. Anyone pair of opposite sides of a trapezium are parallel to each other. There are many real-life examples of trapezium shape that we can see around us. For example, a table whose surface is shaped like a trapezium.
What are the 3 triangles?
Let's start with the three types of triangles that are categorized by the measure of their largest angle. These are the acute, right, and obtuse triangles.
What shape has 3 sides of different lengths?
triangle A triangle whose all three sides are of different lengths is called a scalene triangle.
What are the 3 types of triangle?
According to the lengths of their sides, triangles can be classified into three types which are:
- Scalene.
- Isosceles.
- Equilateral.

| 3 | triangle or trigon |
| 4 | quadrilateral or tetragon |
| 5 | pentagon |
| 6 | hexagon |
What are the names of triangle sides?
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.
What is a kite shape?
In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other rather than adjacent.
What is an oblique triangle?
An oblique triangle is any triangle that is not a right triangle. It could be an acute triangle (all threee angles of the triangle are less than right angles) or it could be an obtuse triangle (one of the three angles is greater than a right angle).
What is scalene triangle?
A scalene triangle is a triangle in which all three sides are in different lengths, and all three angles are of different measures. However, the sum of all the interior angles is always equal to 180 degrees.
What is a triangle with 3 different side lengths called?
If all the three sides of a triangle are of different lengths, then the triangle is called scalene triangle. In △ABC,AB≠BC≠CA. Hence, △ABC is a scalene triangle. Mathematics.
What are the 7 types of triangles?
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. Geometry Sticks.
What are 3 sides of triangle called?
The side opposite to the right angle is the hypotenuse, the longest side of the triangle. The other two sides are called the legs or catheti (singular: cathetus) of the triangle.
What are the 3 sides of a right 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.
What is a trapezium shape?
A trapezium is a convex quadrilateral with exactly one pair of opposite sides parallel to each other. The trapezium is a two-dimensional shape that appears as a table when drawn on a sheet of paper. In Euclidean Geometry, a quadrilateral is defined as a polygon with four sides and four vertices.
What is an obtuse triangle?
An obtuse triangle is a triangle in which one of the angles is an obtuse angle. (Obviously, only a single angle in a triangle can be obtuse or it wouldn't be a triangle.) A triangle must be either obtuse, acute, or right.
What is in obtuse angle?
Obtuse angles measure more than 90 degrees.
Whats is isosceles?
Definition of isosceles 1 of a triangle : having two equal sides — see triangle illustration. 2 of a trapezoid : having the two nonparallel sides equal.
