Geometry 6.4 Day 2 Rhombuses, Rectangles, and Squares

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length. Opposite angles are equal, and adjacent angles are supplementary.

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and all angles measuring 90 degrees.

Front

What is a square?

Back

A square is a special type of rectangle and rhombus where all four sides are equal in length and all angles are 90 degrees.

Front

Are all squares parallelograms?

Back

True. All squares are parallelograms because they have opposite sides that are equal and parallel.

Front

Are all rhombuses rectangles?

Back

False. While all rectangles have opposite sides equal, not all rhombuses have right angles.

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

What is the formula for the area of a rhombus?

Back

Area = (diagonal1 × diagonal2) / 2.

Front

What is the relationship between the diagonals of a rectangle?

Back

The diagonals of a rectangle are equal in length.

Front

How do you find the length of the diagonal in a rectangle?

Back

Use the Pythagorean theorem: Diagonal = √(length² + width²).

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360 degrees.
