## Does triangle have no diagonals?

Regular polygons A triangle has no diagonals. A square has two diagonals of equal length, which intersect at the center of the square.

**How many diagonals does a triangle have?**

Number of Diagonals Formula

Shape | Number of sides, n | Number of Diagonals |
---|---|---|

Triangle | 3 | 3(3−3)/2 = 0 |

Quadrilateral | 4 | 4(4−3)/2 = 2 |

Pentagon | 5 | 5(5−3)/2 = 5 |

Hexagon | 6 | 6(6−3)/2 = 9 |

**Why does an equilateral triangle have no diagonals?**

None – it is a figure with three sides and a diagonal is a line joining opposite angle vertices. The opposing angle vertices of a triangle have the triangle’s sides connecting them, which are sides, not diagonals. No Diagonals are there in a triangle . Hope it’s helpful.

### Can a triangle have diagonals justify?

A triangle has zero diagonals. Diagonals must be created across vertices in a polygon, but the vertices must not be adjacent to one another. A triangle has only adjacent vertices.

**What do you call a triangle with no equal sides?**

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

**How many diagonals does a triangle and a regular hexagon have?**

A hexagon has 9 diagonals. A diagonal of a polygon is a line segment that runs from one vertex of the polygon to another vertex, excluding the sides…

#### Which angle is opposite of the longer leg in a 30 60 90 triangle?

60-degree angle

The hypotenuse is the longest side in a right triangle, which is different from the long leg. The long leg is the leg opposite the 60-degree angle. The figure illustrates the ratio of the sides for the 30-60-90-degree triangle. If you know one side of a 30-60-90 triangle, you can find the other two by using shortcuts.

**How are the diagonals formed in a triangle?**

Triangle does not have any diagonals. Diagonals are formed when the vertices of two non consecutive sides of a figure are joined. But in triangle there is no such pair.

**What do you need to know about the diagonal?**

To learn about diagonals, we must first know that: 1 It (diagonal) is a line segment. 2 Polygons are plane figures having at least three sides and angles and usually, it is used to identify figures having five or more sides and angles. 3 Vertex is a corner of the shape.

## What is a diagonal line in a polygon?

A diagonal line is a line segment that connects the two vertices of a shape, which are not already joined by an edge. It does not go straight up, down or across. In other words, a diagonal is a straight line that connects the opposite corners of a polygon through its vertex.

**How many sides does a triangle have in it?**

Triangle has 3 sides. Finally we can say triangle has no diagonal. In a polygon, line segment joining any two vertices will be either side of the polygon or it will be the diagonal of the polygon.
