Math 8 Q2 BM Practice Test 24-25

Front

What is a 90° clockwise rotation?

Back

A transformation that turns a figure 90 degrees in the clockwise direction around a fixed point.

Front

What is a system of equations?

Back

A set of two or more equations with the same variables that can be solved together.

Front

How do you find the distance between two points after a translation?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²) after applying the translation to the points.

Front

What does it mean when a system of equations has no solution?

Back

It means that the lines represented by the equations are parallel and never intersect.

Front

How do you solve the system of equations y = 2x + 1 and y = 4x - 1?

Back

Set the equations equal to each other: 2x + 1 = 4x - 1, solve for x, then substitute back to find y.

Front

What is a transformation in geometry?

Back

A change in the position, size, or shape of a figure.

Front

What is the result of a 180° rotation?

Back

A transformation that turns a figure 180 degrees around a fixed point, effectively flipping it.

Front

What is a translation in geometry?

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

What does it mean for a system of equations to have all real numbers as a solution?

Back

It means that the equations represent the same line, and any point on that line is a solution.

Front

What is the distance between two points on a coordinate plane?

Back

The length of the straight line connecting the two points, calculated using the distance formula.
