Graphical translation PPT, part 2: translation analysis

Let’s talk about which objects move in translation

Translation definition:

In a plane, a figure moves from one position to another in a certain direction. This movement of a figure is called translation.

Translation only changes the position of the graphic, but does not change its shape or size.

Translate two elements:

direction of translation

translation distance

Talk about it

1. Translate the isosceles right triangle ABC with an area of ​​30cm2 downward by 20cm to obtain △MNP. Then △MNP is a ______ triangle and its area is ______.

2. "Small bamboos are flowing in the middle reaches of the drainage, and towering green mountains are walking on both sides." The graphic transformation involved is __________ transformation.

Graphical translation PPT, part 3: Variation exercises:

As shown in the figure, △ABC becomes △DEF after translation.

So:

(1) The corresponding point of point A is ______

(2) The corresponding point of point B is ______

(3) The corresponding point of point _____ is point F.

(4) The corresponding line segment of line segment AB is line segment ______

(5) The corresponding line segment of line segment BC is line segment ______

(6) The corresponding angle of ∠BAC is ________

(7) The corresponding angle of _______ is ∠F

Graphical translation PPT, part 4 content: Classroom gains and experiences
