What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

Define dilation in geometry.

Back

Dilation is a transformation that alters the size of a figure but keeps its shape, defined by a center point and a scale factor.

Front

What is the relationship between corresponding sides of similar figures?

Back

The ratios of the lengths of corresponding sides of similar figures are equal.

Front

How do you find the scale factor between two similar figures?

Back

The scale factor can be found by dividing the length of a side of one figure by the length of the corresponding side of the other figure.

What is the Pythagorean theorem?

Front

What does it mean for two triangles to be similar?

Front

What is the definition of altitude in a triangle?

Back

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side.

Front

Explain the concept of congruence in geometry.

Back

Congruence in geometry means that two figures have the same shape and size, and can be made to coincide by rigid transformations.

What is the formula for the perimeter of a rectangle?
