S1 Final Exam Review

Front

What is the midpoint formula for two points (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

How do you find the length of a line segment between two points (x1, y1) and (x2, y2)?

Back

Length = √((x2 - x1)² + (y2 - y1)²)

Front

What are the properties of a parallelogram?

Back

Opposite sides are congruent and parallel; opposite angles are congruent.

Front

What is the definition of a square?

Back

A square is a quadrilateral with four congruent sides and four right angles.

Front

What transformation occurs when a point (x, y) is reflected over the y-axis?

Back

The new point is (-x, y).

Front

What is the transformation for a reflection over the x-axis?

Back

The new point is (x, -y).

Front

What is a translation in geometry?

Back

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

Front

What is the formula for the distance between two points in a coordinate plane?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)
