## What is the perimeter of a triangle with vertices 0 4 0 0 and 30?

So, the correct answer is “12 units”.

## How do you find the area of a triangle with 3 coordinates?

How Do You Find the Area of a Triangle With 3 Coordinates? Area of triangle with 3 points is: A = (1/2) |x1 1 (y2 2 − y3 3 ) + x2 2 (y3 3 − y1 1 ) + x3 3 (y1 1 − y2 2 )|, where (x1 1 ,y1 1 ),(x2 2 ,y2 2 ), and (x3 3 ,y3 3 ) are the coordinates of vertices of triangle.

**How do you find the sides of a triangle given the vertices?**

We have to distance formula which can tell the distance between 2 points. d = √(x2 – x1)^2 + (y2 – y1)^2. = √26. Therefore, the length of the sides of the triangle are √26,√29 and √101.

### How do you write coordinates for a triangle?

Any coordinate pair is written in the form 𝑥, 𝑦. We write the 𝑥-coordinate first, followed by the 𝑦-coordinate. This is often known as along the corridor and up the stairs. The point 𝐴 is four units along the 𝑥-axis and six units up the 𝑦-axis.

### What is the area of a triangle with vertices at 5 0 8 0?

The area is “6 square units”.

**What is the perimeter of triangle with vertices?**

Perimeter= 3 + 5 + 4 = 12 To find the perimeter of the triangle, find the lengths of each side of the triangle using the distance formula. Use the distance formula to find the length between point A and B, B and C, C and A. Then add all three lengths together to get the perimeter.

#### How many vertices are there in a triangle?

3

Triangle | |
---|---|

Edges and vertices | 3 |

Schläfli symbol | {3} (for equilateral) |

Area | various methods; see below |

Internal angle (degrees) | 60° (for equilateral) |

#### Which expression represents the distance between the points 0 A and a 0 on a coordinate grid?

√

Summary: The expression which represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a2 + 52).

**How do you calculate the sides of a triangle?**

The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.

## How do you find the vertices of a triangle?

The three different intersecting points or corners are called the vertices of a triangle. A triangle has three vertices or corners where one line endpoint meets another. If (x 1, y 1 ), (x 2, y 2 ), and (x 3, y 3) are the midpoints of the sides of a triangle on the coordinates, we can find the vertices using the following formula:

## How is a triangle solved in a calculator?

The calculator uses the following solutions steps: From the three pairs of points calculate lengths of sides of the triangle using the Pythagorean theorem. The continue calculation of the unknown parameters of the triangle using the identical procedure as in SSS triangle calculator.

**How to find the square root of a triangle?**

Input vertices and choose one of seven triangle characteristics to compute. 1 . Input three points and select a value to compute. 2 . You can input integers ( 10 ), decimals ( 10.2 ), fractions ( 10/3) and Square Roots – (use letter ‘r’ as a square root symbol). Example: NOTE: To input square root symbol type letter ‘r’. For example: , ,.

### How do you find the area of a triangle?

The most general way to find the area of a triangle given three or more dimensional coordinates is to use Archimedes’ Theorem. A triangle with squared sides A, B, and C has an area a that satisfies: Given the coordinates of the vertices of a triangle. This reference tells you how to compute the Cross product.
