What is the definition of similar figures in geometry?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

How do you determine if two figures are similar using common ratios?

Back

To determine if two figures are similar, calculate the ratios of the lengths of corresponding sides. If all ratios are equal, the figures are similar.

What does it mean if the ratio of two sides is not equal to the ratio of another pair of sides?

Back

If the ratio of two sides is not equal to the ratio of another pair of sides, the figures are not similar.

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape. Common transformations include translation, rotation, reflection, and dilation.

What is the sequence of transformations that maps figure A to figure B if it involves reflections?

Back

The sequence of transformations that maps figure A to figure B could involve reflecting across the x-axis followed by reflecting across the y-axis.

What does SAS stand for in geometry?

Back

SAS stands for Side-Angle-Side, which is a criterion for triangle similarity and congruence.

How can you identify the number of lines of symmetry in a shape?

Back

To identify the number of lines of symmetry in a shape, look for lines that can be drawn through the shape such that one side is a mirror image of the other.

Front

What is the significance of having only one line of symmetry in a shape?

Back

Having only one line of symmetry means that the shape can be divided into two identical halves along that line.

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.

Front

What is a reflection in geometry?

Back

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