1.11 Quiz: Use Algebra to Describe Geometry 2

The coordinates of the vertices of △ABC△ABC are A(−4, 6)A(−4, 6), B(−2, 2)B(−2, 2), and C(−6, 2)C(−6, 2). The coordinates of the vertices of △A′B′C′△A′B′C′are A′(2, 6)A′(2, 6), B′(0, 2)B′(0, 2), and C′(4, 2)C′(4, 2). Drag and drop the answers into the boxes to correctly complete the statement. A sequence of transformations that maps △ABC△ABC to △A′B′C′△A′B′C′is a

1. Reflection across the y-axis 2. Translation 2 units left

Graph the image of the given triangle after the transformation with the rule (x, y)→(−x, y)(x, y)→(−x, y). Select the "Polygon" button from the tool bar to plot your triangle. You may use the "Move" button to move the triangle after it is created.

(-3, 4) (-4, 7) (-8, 2) X axis always comes first

Drag and drop the answers into the boxes to correctly complete the statement.A sequence of transformations that maps △ABC to △A′B′C′ is a _____ followed by a ______.The two triangles are on a coordinate plane. The horizontal x-axis ranges from negative 5 to 5 with an increment of 1. The vertical y-axis ranges from negative 5 to 5 with an increment of 1. A dashed triangle has vertex A prime at begin ordered pair negative 1 comma negative 4 end ordered pair, vertex B prime at begin ordered

rotation of 90° counterclockwise, translation 2 units right

What are the coordinates of the point (−4, 2)(−4, 2) after a translation 2 units left and 2 units up?

(−6, 4)

Graph the image of the given triangle after the transformation with the rule (x, y)→(x−6, y−4)(x, y)→(x−6, y−4). Select the "Polygon" button from the tool bar to plot your triangle. You may use the "Move" button to move the triangle after it is created.
