Scalene triangle QRS is reflected across a horizontal line to produce triangle LMN. The length of side RS is equal to the length of side LM.
What is, "false"?
100
Parallelogram RSTU is rotated 180º clockwise about vertex R. The image has 1, 2, 3 or 4 pairs of parallel sides?
What is, "2 pairs"?
100
A triangle has vertices (-4, 4), (-7, -2), and (-4, -2). These are its image's coordinates after being translated 4 units down and reflected across the y-axis.
What is, "(4, 4), (4, -1), (7, -1)"?
200
Triangle ABC is reflected across a vertical line and then translated 8 units down to produce triangle EFG. Angle ABC is congruent to angle EFG. The measure of angle CBA is 8º less than the measure of angle GFE.
What is, "false"? While it is true that angle ABC IS congruent to angle EFG, the measure of angles CBA equals GFC because they are congruent.
200
The reason the mathematician was late for work.
What is, "he took the Rhombus"?
200
A rectangular picture frame is moved 5 feet to the right. This is how many angles the picture frame has now.
What is, "4"?
300
Point (2, –4) is reflected across the x-axis. These are the coordinates of the image.
What is, "(2, 4)"?
300
Coordinates are transformed using the rule (x, y) --> (-x, -y). This is the kind of transformation that occurs along with the change in degrees.
What is a "180-degree rotation" (about the origin)?
300
The reason the triangle was always correct.
What is, "it was a right triangle"? Or, perhaps "it was a perfect triangle"?
400
After Hailey rotates a 5-inch square piece of wood 1/4-turn clockwise, this is the length of each side.
What is, "5 inches"?
400
The reason one angle said to the other angle, "You look marvelous, dahling."
What is, "it was a complementary angle"?
400
Triangle with vertices (-2, 3), (5, 4), and (-1, -1) is translated using rule (x, y)-->(x - 3, y + 4). These are the coordinates of the image.
What is (-5, 7), (2, 8), and (-4, 3)?
500
What is, "C"?
500
The given trapezoid is rotated 270º counterclockwise about the origin. The purple "nose" of its image is in this quadrant.
What is, "Quadrant 4"?
500
The reason the square loved the 40-degree angle.
What is, "it was acute angle."
