## How do you find the area of a triangle given 3 points?

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.

## What is the simplest polygon?

In geometry, a simple polygon /ˈpɒlɪɡɒn/ is **a polygon that does not intersect itself and has no holes**. That is, it is a flat shape consisting of straight, non-intersecting line segments or "sides" that are joined pairwise to form a single closed path. ... The number of edges always equals the number of vertices.

## What does the midpoint formula find?

The midpoint formula in coordinate geometry is defined as the formula **to find the center point of a straight line, using the coordinates of its endpoints**. The midpoint formula is used to find the halfway that is a point that divides the line into two equal parts.

## Does shoelace theorem work in 3D?

This research takes The Shoelace Formula (also known as Surveyor's area formula) — a formula to find the area of a polygon in 2D (Braden, 1986) — and **modified it to work in 3D**. This new formula has been mathematically proven and tested with a calculation of different kinds of shapes using a computer program.Mar 12, 2020

## What is the equation to find the distance between two points?

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as **d=√((x_2-x_1)²+(y_2-y_1)²)** to find the distance between any two points.

## What is meant by convex polygon?

Definition of convex polygon

: **a polygon each of whose angles is less than a straight angle**.

## What is the center of mass of a triangle?

The centre of mass is also called the centre of gravity. The centre of mass of the triangle is **the point at which the mass of the triangle will balance**. To understand the “centre of mass” of a triangle, let us imagine balancing triangular cardboard on the pencil tip.
