How do you solve translations in geometry?

How do you solve translations in geometry?

In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) .

What is the rule for translation in math?

In a translation, every point of the object must be moved in the same direction and for the same distance.

What are the rules of translations?

What are the basic rules of translation in any language?

  • Avoid translating first names.
  • Beware of false cognates.
  • Not every word has a literal translation.
  • English / Portuguese.
  • Spanish / Portuguese.
  • German / Portuguese.

What is the algebraic rule for reflection?

A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y) .

How do you describe translations?

A translation is a type of transformation that moves each point in a figure the same distance in the same direction. Translations are often referred to as slides. You can describe a translation using words like “moved up 3 and over 5 to the left” or with notation. There are two types of notation to know.

What is a positive rotation?

A positive rotation tells you to go counter-clockwise while a negative rotation tells you to go clockwise.

Is rotation clockwise positive?

Clockwise rotations are denoted by negative numbers. Counterclockwise rotations are denoted by positive numbers. Note that the direction of rotation (CW or CCW) doesn’t matter for 180 and 360-degree rotations, since they will both bring you to the same spot (more on this later).

How do you know which way a fan goes?

When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top.

How do you tell if your fan is going the right way?

If you are unsure if your fan is turning the correct direction, stand directly under the fan and look up. If the fan is moving counterclockwise and you feel a rush of air, it’s in the correct setting for summer. If you don’t feel much air movement, it’s possible that the fan is spinning in the wrong direction.

Should ceiling fan switch be up or down in winter?

In the winter, you actually want that switch in the up position, and in the summer, it should be in the down position as shown above. In the cooler months, having the blades circulating in a clockwise direction will create an updraft.
