geometry chapter 8-10

Geometry

For the geometry we learn about angle, types of angle, line, point, ray, and  more.

Then we also do the reading mathematics for the chapter 10.

An angle measures the amount of turn. the types of angles are acute angle, obtuse angle, right angle, straight angle, and reflex angle.

Acute angle is an angle that is less than 90°
Obtuse angle is an angle that is more than 90°
Right angle is an angle that has an measurement of 90°
Straight angle is an angle that is precisely 180°
Reflex angle is an angle that is greater than 180°

Line is a long thin mark made by a pen, pencil, etc. The characteristic of a line is straight, has no thickness, extends in both directions without end.

Point is an exact location that has no size but only position. Points usually has a name, Often named by a letter like "A" or "B" etc.

Ray is a  line with a start point but no end point.

We also make a drawing using coordinates in 8:02 fun spot
the result will be a Spartacus face.
