Review - Transformations and Similar Triangles

Front

What is a similarity statement for triangles?

Back

A similarity statement indicates that two triangles have the same shape but may differ in size, denoted as ΔABC ∼ ΔDEF.

Front

What does it mean if two triangles are similar?

Back

Two triangles are similar if their corresponding angles are equal and their corresponding sides are in proportion.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is a vertical stretch transformation?

Back

A vertical stretch transformation occurs when the y-coordinates of a figure are multiplied by a factor greater than 1, making the figure taller.

Front

What does congruent mean in geometry?

Back

Congruent figures are those that have the same shape and size.

Front

What is the effect of shifting a graph down by 7 units?

Back

Shifting a graph down by 7 units means subtracting 7 from the function, resulting in f(x) = x - 7.

Front

What is a reflection transformation?

Back

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

Front

What is the difference between congruent and similar figures?

Back

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

Front

What is the parent function of f(x) = x?

Back

The parent function f(x) = x is a linear function that represents a straight line through the origin with a slope of 1.

Front

What does it mean for two figures to be NOT congruent?

Back

Two figures are NOT congruent if they differ in either size or shape.
