Translating Shapes on the Coordinate Plane

Mr. Mason explains how to translate a triangle on the coordinate plane by moving it nine units to the right and four units down. He describes translation as a geometric function that moves an object without altering its shape or size. The process involves adding to the x-values and subtracting from the y-values of the triangle's points. The video concludes with a verification of the new coordinates and a recap of the translation process.

What does translating an object on the coordinate plane involve?

• Rotating the object

• Reflecting the object

• Moving the object without altering its shape

• Changing the shape of the object

How is a movement to the right represented on the coordinate plane?

• Subtracting from the x-value

• Adding to the y-value

• It is decreased

• It is increased

• It remains the same

• It is multiplied
