Front

What is the result of a 90-degree counterclockwise rotation of a point (x,y)?

Back

(x,y) = (-y,x)

Front

How do you write the algebraic notation for a scale factor of 3?

Back

(x, y) goes to (3x, 3y)

Front

What is the equation of a line that is perpendicular to y = 3x - 12 and passes through (-9,2)?

Back

y = (-1/3)x - 1

Front

What does HL stand for in triangle congruence?

Back

HL stands for Hypotenuse-Leg, a criterion for proving triangles congruent.

Front

If y + z = 180 and y = 76, what is the value of z?

Back

z = 104

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

What is the Pythagorean theorem?

Back

a² + b² = c², where c is the hypotenuse of a right triangle.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for proving triangles congruent.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)
