After a reflection over the y-axis, the point (5, −3) becomes this point.
What is (−5, −3)?
This is the slope of a horizontal line.
What is 0?
A triangle has vertices A(2, 3), B(5, 3), and C(2, 7). After a 90° clockwise rotation about the origin, what are the new coordinates of point C?
What is (7, −2)?
This transformation flips a figure over a line.
What is a reflection?
On a coordinate plane, a dilation centered at the origin maps (−2, 5) to (−6, 15). What is the scale factor?
What is 3?
The volume formula for a cylinder includes this famous irrational number.
What is π (pie)?
Triangle A has vertices (1,2), (4,2), and (1,6). Triangle B has vertices (−1,2), (−4,2), and (−1,6). What single transformation maps Triangle A to Triangle B?
What is a reflection over the y-axis?
The Pythagorean Theorem is written as this equation.
What is a² + b² = c²?
A triangle has side lengths 5, 7, and 9. Another triangle has side lengths 10, 14, and 18. Are the triangles similar? Explain.
What is yes, because each side length is multiplied by 2 (proportional sides)?
This transformation slides a figure without turning or flipping it.
What is a translation?
