Watch this video to learn how a cinema projector works and how a film appears on the screen.
Line e is given. Let’s plot a line parallel to line e 2 cm away.
Axis t and point P are given. Let’s plot the mirror image (point P’) of point P across axis t.
We produce carbon dioxide with sodium hydrogen carbonate and citric acid. It is a skyrocketing success!
We prepare a special “elephant toothpaste” with some hydrogen peroxide, liquid soap and food colouring.
Line e is given. Plot point P at a distance of 2 cm from line e.
Axis t and triangle ABC are given on a particular plane. Let’s plot the mirror image of triangle ABC.
Axis t and a circle with centre O and radius r are given on a particular plane. Let’s plot the mirror image of the circle.
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.
Axis t and line segment AB are given on a plane. Let’s plot the mirror image of line segment AB across t.
Is there a difference between the weight of a plastic bottle filled with air and the weight of a crushed one?
Let’s construct the perpendicular bisector of a 6-cm-long line segment.
In this video, we plot the angle bisector of a given angle.
Let’s copy a given alpha convex angle onto ray f with starting point F.
Theseus’s battle with the Minotaur, a creature with the head of a bull and the body of a man, in the mysterious labyrinth.
Why did the statue of a she-wolf and two little boys become an iconic symbol of Rome? This video is about their story.
A mummy is a dead body that has not decomposed as a result of embalming or special environmental factors.
