Geometry - S1 - Practice Final Exam (Fall 2024)

Front

What is the definition of a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What is a translation?

Back

A translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

Front

What is a reflection?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is a dilation?

Back

A dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What is the axis of symmetry?

Back

The axis of symmetry is a line that divides a shape into two mirror-image halves.

Front

How do you find the axis of symmetry for a quadratic function?

Back

The axis of symmetry for a quadratic function in the form y = ax^2 + bx + c is given by the formula x = -b/(2a).

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written in the form (x, y).

Front

What does it mean to round a number to the tenth?

Back

Rounding a number to the tenth means to round it to one decimal place, which is the first digit to the right of the decimal point.
