Field geometry Flat is the study of images on a two-dimensional surface – that is, on a plane.
You can think of the plane as a sheet of paper with no thickness at all. Technically, the plane doesn’t end at the edge of the paper – it goes on forever.
Make some points
A point is the location on the plane. It has no size or shape.
Even if a dot is actually too small to see, you can visually represent it in an image by using dots.
When two lines intersect, they share a point. In addition, each corner of the polygon is a point.

Know your dialogue
A line – also call straight line – more or less as the name suggests; it marks the shortest distance between two points, but extends indefinitely in both directions.
It has length but not width, making it a one-dimensional (1-D) figure.
Given two points, you can draw exactly one line that goes through them. In other words, two dots determine a line.
When two lines intersect, they share a point. If two lines do not intersect, then both parallel, which means the two lines remain the same distance everywhere.
A good visual aid for parallel lines is a set of railroad tracks.
In geometry, you draw a line with arrows at both ends.
The arrows at either end of the line mean that the line continues forever.
A line segment is the part of the line that has an end point.
A ray is the part of a line that starts at a point and extends far in one direction, kind of like a laser. It has one endpoint and one arrow.
Determine the angle
A corner formed when two rays extend from the same point.
Angles are commonly used in carpentry to measure the angles of objects. They are also used in navigation to indicate a sudden change of direction. For example, when you are driving, it is common to distinguish between “sharp” or “not very sharp” turning angles.
The sharpness of an angle is usually measured in level . The most common angles are right angles. day – the angle on the corner of a square – which is an angle of 90 degrees:
An angle that has less than 90 degrees – that is, an angle that is sharper than a right angle – is called acute angle like this:
An angle that is greater than 90 degrees – that is, an angle that is not as sharp as a right angle – is called blunt angle as seen here:
If an angle is exactly 180 degrees, then it forms a straight line and is called right angle .
A shape is a closed geometric figure that has an inside and an outside. Circles, squares, triangles, and larger polygons are examples of shapes.
Many plane geometries focus on different types of shapes.

Field Geometry Formulas
- Polygon interior angle (total of all angles in the polygon):
The total size of the interior angles = 180 (Sum of angles – 2)
- The Pythagorean Theorem (where a and b is a foot, and c is the hypotenuse):
a 2 + b 2 = c 2
- Area and perimeter of square side s :
A = s 2
P = 4 dtk
- Area and perimeter of side rectangle l and w :
A = lw
P = 2 l + 2 w
A = bh
- Diameter, area and circumference of a circle:
- Volume and surface area of the cube:
V = s 3
A = 6 dtk 2
- Volume and surface area of the box:
V = etc.
A = 2 lw + 2 lh + 2 wh
- Volume and surface area of the sphere:
V = A b h
