What does the Triangle Proportionality Theorem state?

Back

If a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

Front

What is the converse of the Triangle Proportionality Theorem?

Back

If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

Front

How do you determine if two line segments are parallel using proportions?

Back

If the ratios of the lengths of the segments are equal, then the line segments are parallel.

Front

What is a similarity statement in geometry?

Back

A similarity statement indicates that two figures are similar, meaning they have the same shape but possibly different sizes.

Front

What does it mean for two triangles to be similar?

Back

Two triangles are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is a dilation in geometry?

Back

A dilation is a transformation that changes the size of a figure but not its shape.

Front

How does a dilation affect the lengths of sides in a polygon?

Back

A dilation multiplies the lengths of the sides by a scale factor.

Front

What happens to the angles of a polygon during a dilation?

Back

Dilations do not change the angles of a polygon.

Front

What is a scale factor in dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Back

Line segment TU is parallel to line segment RS.
