Geometry Final 1st Semester

Front

What is a 270° clockwise rotation?

Back

A transformation that turns a figure 270 degrees in the clockwise direction around a fixed point.

Front

How do you translate a point 6 units down and 3 units left?

Back

To translate a point, subtract 6 from the y-coordinate and 3 from the x-coordinate.

Front

If point T is at (2, 5), where is T' after translating 3 units right and 6 units up?

Back

T' would be at (5, 11).

Front

What are undefined terms in geometry?

Back

Basic concepts that are not formally defined but are understood intuitively, such as point, line, and plane.

Front

What is the distance formula?

Back

The distance between two points (x1, y1) and (x2, y2) is given by the formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is a point in geometry?

Back

A point is a location in space that has no size or dimension.

Front

What is a line segment?

Back

A line segment is a part of a line that has two endpoints.

Front

What is a plane in geometry?

Back

A plane is a flat, two-dimensional surface that extends infinitely in all directions.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, or reflection.

Front

What does it mean to translate a shape?

Back

To translate a shape means to slide it from one position to another without rotating or flipping it.
