6.G.3 Review

Front

What is the formula to calculate the area of a triangle given its vertices?

Back

Area = 1/2 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|, where (x1, y1), (x2, y2), (x3, y3) are the vertices.

How do you find the coordinates of a missing vertex in a square?

Back

Use the properties of a square: all sides are equal and angles are 90 degrees. If you have three vertices, you can find the fourth by maintaining these properties.

Front

What are the properties of a parallelogram?

Back

Opposite sides are equal and parallel, opposite angles are equal, and the diagonals bisect each other.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 * (length + width).

Front

What defines a square?

Back

A square is a quadrilateral with all sides equal and all angles equal to 90 degrees.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

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

Front

How can you determine if four points form a rectangle?

Back

Check if opposite sides are equal and all angles are 90 degrees.

Front

What is the area of a rectangle?

Back

Area = length * width.

Front

What is the significance of ordered pairs in geometry?

Back

Ordered pairs represent points in a coordinate plane, defining their position based on x (horizontal) and y (vertical) values.

Front

How do you identify a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.
