What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, but may be in different positions.

Front

What is the definition of intersecting lines?

Back

Intersecting lines are lines that cross each other at one point, resulting in one solution for a system of linear equations.

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they have the same slope but different y-intercepts.

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but keeps its shape, using a scale factor.

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that scales, or multiplies, the coordinates of a figure during a dilation.

How do you determine if two triangles are congruent using transformations?

Back

Two triangles are congruent if one can be transformed into the other using rotations, reflections, or translations.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, b) where b is the y-coordinate.

Front

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

Back

A system has no solution if the lines are parallel, meaning they never intersect.

Front

What is the solution to a system of equations with infinitely many solutions?

Back

Infinitely many solutions occur when the equations represent the same line, meaning they coincide.
