Translations Between Triangles

In Activity 5.1, students learn about translating coordinates by identifying which translations move triangle T to triangle U. Two translations correctly move corresponding points from T to U, while one incorrectly moves from U to T, and another moves within the same triangle. The video provides detailed explanations and examples of both correct and incorrect translations, helping students understand the concept of coordinate translation.

What is the main task in Activity 5.1?

• Identify the correct translations from triangle T to triangle U.

• Identify the translations that do not move any points.

• Identify the correct translations from triangle U to triangle T.

• Identify the translations within the same triangle.

Which translation correctly moves a point from triangle T to triangle U?

• From point (2, 1) to point (-2, -1)

• From point (0, -1) to point (-4, -3)

• From point (-4, -3) to point (0, -1)

• From point (1, 2) to point (2, 1)

Which translation is correct according to the video?

• From point (0, -1) to point (-4, -3)

• From point (2, 1) to point (-2, -1)

• From point (1, 2) to point (2, 1)

• From point (-3, 0) to point (1, 2)

What is incorrect about the translation from point (2, 1) to point (-2, -1)?

• It does not move any point.

• It moves a point to a non-corresponding point.

• It moves a point from triangle U to triangle T.

• It moves a point within the same triangle.

Why is the translation from point (1, 2) to point (2, 1) incorrect?

• It moves a point from triangle U to triangle T.

• It moves a point to a corresponding point.

• It moves a point to a non-corresponding point within the same triangle.

• It does not move any point.

Which of the following is a correct translation from triangle T to triangle U?

• From point (2, 1) to point (-2, -1)

• From point (0, -1) to point (-4, -3)

• From point (-4, -3) to point (0, -1)

• From point (1, 2) to point (2, 1)

What is the result of translating point (-4, -3) in the correct direction?

• It moves to point (-2, -1).

• It moves to point (1, 2).

• It moves to point (0, -1).

• It moves to point (2, 1).

Which translation incorrectly moves a point within the same triangle?

• From point (1, 2) to point (2, 1)

• From point (-4, -3) to point (0, -1)

• From point (2, 1) to point (-2, -1)

• From point (-3, 0) to point (1, 2)

What is the correct translation for moving point (-3, 0) to its corresponding point?

• To point (-2, -1)

• To point (1, 2)

• To point (0, -1)

• To point (2, 1)

Which translation is not a correct move from triangle T to triangle U?

• From point (-3, 0) to point (1, 2)

• From point (2, 1) to point (-2, -1)

• From point (-4, -3) to point (0, -1)

• From point (1, 2) to point (2, 1)
