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

What ensures that the translated object remains congruent to the original?

• Moving each point a different distance

• Changing the shape of the object

• Moving each point the same distance and direction

• Rotating the object

What is the correct sequence of actions for translating an object on the coordinate plane?

• Rotate, reflect, then translate

• Translate, then resize

• Translate without rotating or reflecting

• Reflect, then translate

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

• Subtracting from the x-value

• Adding to the y-value

• Adding to the x-value

• Subtracting from the y-value

What happens to the y-value when an object is moved down?

• It is decreased

• It is increased

• It remains the same

• It is multiplied

After translating a triangle 9 units right and 4 units down, what is the new x-coordinate of a point initially at -8?

• -12

• -8

• 1

• 5

What is the new y-coordinate of a point initially at 2, after translating the object 4 units down?

• 6

• -2

• 2

• -6

If a point on a triangle is initially at (-4, 2) and the triangle is translated 9 units right, what is the new x-coordinate?

• 13

• 5

• -13

• -4

What is the result of translating an object upwards on the coordinate plane?

• Decrease in x-value

• Increase in y-value

• Increase in x-value

• Decrease in y-value

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

• Decrease in x-value

• Increase in x-value

• Increase in y-value

• Decrease in y-value
