Online free math

Let us learn online geometry tutor

Online geometry tutors teach the geometric concept to students. Tutors also help to solve their practices problems and clarify their doubts in geometry. In this section we are going to see about the concept of the Geometry. It is used to study about the relationships among shapes and their properties.

Point, line, plane, angle and ray are the topics covered by geometry in this section. Let us see the brief notes about online geometry tutor.
You can also get more details on solve geometry problems
The point is denoted by a dot. It also denoted by using named a capital letter. A point denotes location only; it has zero size.

A line or straight line can be consideration of as a linked set of infinitely many points. It extends considerably far in two reverse directions.
our next post will be on geometry answers solved

Learning reflection definition

Let us learn reflection definition

Reflection is defined as, the ray which passes on a object and get reflected and it forms a reflective ray. This ray is called as mirror image of the original image, which passes through it. The mirror image has the same properties as like the original image.

A triangle is a basic figure and most essential type in the shapes of geometry. It is one of the types of polygons. Triangles are figures which have three sides and three corners, which are line segments. you can also get help with logical mathematical intelligence
The triangles are of many types, they are Right-angled triangle, acute triangle, obtuse triangle, equilateral triangle, isosceles triangle, and scalene triangle. Here we see about the reflective triangles and their properties.

Our next blog will help you with Radical Definition

Learning Point slope form

Let us learn about point slope form

The other format for equation of straight line is called as a point slope form .suppose the given is one point and slope then the point slope form can be written as,

General format:
y - y1 = m (x-x1)
Here
(x1,y1) line passes through the point
m represent the slope of the line
Here we are going to learn about how to writ e point slope form and its example problems.
There are many calculators available for solving point slope form.

Also get information on acres to square feet

Calculate the equation of straight line passes through the point (2, 1) and the slope of the line is 3
Solution:
Given x1=2 and y1=1
Slope (m) =3
We know that point slope form equation y - y1 = m (x-x1)
Substitute th
e slope and point’s value in the above formula we get,

y-1=3 (x-2)
y -1 = 3x -6
Add both sides +1
y– 1+1 = 3x -6 +1
y = 3x-5
Therefore the equation of a line is y = 3x-5
