Due to the effect of both exogenic and endogenic forces, rocks constantly change. This is called the rock cycle.
Mayflies or shadflies are insects whose larval stage usually lasts 1-3 years, which they spend in freshwater.
Axis t and line segment AB are given on a plane. Let’s plot the mirror image of line segment AB across t.
The recording shows a more than 2000-year-old gilded sarcophagus. You can see the names of the deceased and his protecting gods on the coffin.

A compound called sodium azide is responsible for the operation of airbags.
The words hot and ice together? There must be a trick somewhere. Let’s have a look.
Both line e and point P, which is situated on it, are given. Let’s plot line g to include point P on line e so that it is perpendicular to line e.
Both line e and point P, which is not situated on line e, are given. Let’s plot line g such that it passes through point P and is perpendicular to line e.
In this experiment, we use buoyancy to study the balance of two glasses of water.
Let’s plot line g such that it is parallel to line e and passes through point P.
Let’s construct a rhombus such that one of its sides lies on line e and point P is one of the vertices on the opposite side.
