Reflection and Translation of a Triangle

The video tutorial covers transformations, focusing on reflecting and translating triangles on a graph. Part A involves reflecting triangle S over the line y = X and labeling it as triangle R. The process includes drawing the line, reflecting vertices, and ensuring correct labeling. Part B requires translating triangle S using a vector (-4, -6) to form triangle T, maintaining orientation and labeling. The tutorial emphasizes accuracy in vertex placement and labeling, highlighting common errors in reflection and translation tasks.

What is the line of reflection used in Part A of the transformations question?

• y = X

• y = -X

• x = Y

• x = -Y

When reflecting a shape, what is the first step according to the tutorial?

• Label the new shape

• Move the shape horizontally

• Draw the line of reflection

• Rotate the shape

How do you determine the new position of a vertex when reflecting it over the line y = X?

• Move it horizontally

• Move it vertically

• Move it diagonally

• Move it in a circle

What is the vector used for translating triangle S in Part B?

• (6, 4)

• (4, 6)

• (-4, -6)

• (-6, -4)

What does the first number in the translation vector represent?

• Diagonal movement

• Rotational movement

• Vertical movement

• Horizontal movement

What is a common error when reflecting shapes according to the tutorial?

• Moving along the Y axis

• Moving along the X axis

• Moving in a circle

• Moving diagonally

What is crucial to ensure when labeling the new triangles in both parts of the question?

• Correct orientation

• Correct size

• Correct color

• Correct label
