What does it mean for two triangles to be congruent?

• Two triangles are congruent if they have the same size and shape, which can be proven through transformations.

• Two triangles are congruent if they have the same perimeter but different angles.

• Two triangles are congruent if they have different sizes but the same shape.

• Two triangles are congruent if they are both equilateral.

What is the effect of a positive slope on a line in a graph?

• A positive slope indicates that as x increases, y also increases, resulting in an upward trend.

• A positive slope indicates that as x increases, y decreases, resulting in a downward trend.

• A positive slope indicates that y remains constant as x increases, resulting in a horizontal line.

• A positive slope indicates that y increases at a decreasing rate as x increases.

What does a negative slope indicate in a scatter plot?

• A negative slope indicates that as the x-values increase, the y-values decrease.

• A negative slope indicates that as the x-values increase, the y-values increase.

• A negative slope indicates that there is no relationship between x and y values.

• A negative slope indicates that y-values are constant regardless of x-values.

What transformation maps triangle A onto triangle B if it involves a reflection over the x-axis followed by a translation?

• A reflection over the x-axis, then a translation 6 units to the left.

• A rotation 90 degrees clockwise, then a translation 4 units to the right.

• A reflection over the y-axis, then a translation 3 units up.

• A translation 5 units to the right, then a reflection over the x-axis.
