I am very happy to be participating in the Steemit Learning Challenge Season 23.I am also very happy that all the creative content has been selected here this time.

Dear friends, I will join SLC S23 Week1 || Geometry with GeoGebra: Points, Lines, and Angles... right now, where my dear teacher @sergeyk has taught me very beautifully.I will join that challenge and try to show some great activities in the first week, God willing.Without further ado, let me get straight to the solutions to my homework.

Task №1 What is geometry? When and why did it appear? How did you study geometry in school? Were you familiar with any geometry software?

Geometry is a branch of mathematics that deals with shape, properties of shape, position, and spatial relationships.
Geometry originated in ancient Egypt and Babylon.But 300 years before BC, the Greek scholar Euclid mentioned it in his famous book Elements.Which is mainly used for several purposes including land measurement and astronomy.

The geometry curriculum was taught very well in school.The notable thing is that both theoretical and practical subjects were taught there with great efficiency.I clearly remember when I was in seventh grade, everyone in the classroom got angry over just one question.The question was, "Which country's scholars spoke of Euclid?" but I couldn't say.However, at that time, geometry was taught on the blackboard using memorized geometry textbooks and cut out compass scales, etc., and it was completed very carefully.

I am familiar with two geometric software, one is AutoCAD and the other is GeoGebra.However, I haven't done much with Geo Zebra because I don't have much experience here, but I have had to look at it occasionally because I'm studying AutoCAD engineering.I usually use AutoCAD in my engineering to complete engineering drawings, and the use of AutoCAD is very important in creating textile patterns.

Task №2 Explain different geometric primitives (point, line, angle, segment, ray) and illustrate them in GeoGebra.Explain various geometric primitives (point, line, angle, segment, ray) and illustrate them in GeoGebra.

point:

A point is the most basic element of geometry, defining only position. A point has no length, width, or depth.

line

A line is a straight path that extends indefinitely through two points, meaning it has no beginning or end.

angle

An angle is the open space between two rays or lines that start from a common point. The size of the angle is measured in degrees.

segment

A segment is a part of a line that is bounded by two fixed points.

ray

A ray is a part of a line that starts at a specific point and extends to infinity in a specific direction.

Task №3 Construct an arbitrary angle, then extend one side to create a supplementary ray—show that the sum of adjacent angles is always 180 degrees.Construct an angle with two supplementary rays—show that the resulting vertical angles are always equal.

An arbitrary angle and complementary ray were created using GeoGebra.

First you need to create a point.
We need to draw a line which will be known as AC. Now from this point we need to draw a line upwards called A D.Here, one angle will be formed by BAD and another one will be drawn which will be parallel to it.And they will create each other.

Task №4 Construct parallel lines and perpendicular lines. Construct two lines intersected by a third line (a transversal). Label the angles on the figure (using letters, numbers, or colors). Name the pairs of angles that have special names.

Construct parallel lines and perpendicular lines.
To draw, we first need to take two ropes that are equally fluid with the ground.You have to draw two lines in such a way that they are parallel to the ground and a third line has to be drawn between them that intersects each other.

The intersection points of the land and the texts are marked, but I can't use Geo Zebra properly, so I can't do the numbering. I'll just try to illustrate the things used here with pictures.I told him that although geometry activities don't work like this, I will try to do my best from tomorrow.

Task №5 Construct the intersection of two segments. Ensure that the intersection point is always displayed, even if it does not lie on the segments themselves. If the intersection point lies outside the segments, represent this with dashed lines.As I demonstrated here.

First, a point must be determined.And you have to draw a segment from that point.After drawing a segment very parallel to the ground, you need to set it aside and draw another full line with a point in the middle of the segment.And it remains to be seen how much of a visual show they will actually have to put on.

I didn't learn much from this geometry class. Even though I was very focused, everything seemed chaotic to me. I had to follow the lessons from the previous classes to understand them better. These were the lessons of my educational life.But I tried my best with my knowledge and thank you to the teacher for organizing such a beautiful challenge.
