Parallelograms, Rectangles, Rhombi, and Squares!

Front

What is a rhombus?

Back

A rhombus is a type of quadrilateral where all four sides are of equal length, and opposite angles are equal.

Front

If AB = 4x + 3 and BC = 9x - 27 in a rhombus, how do you find x?

Back

Set AB equal to BC: 4x + 3 = 9x - 27. Solve for x to find x = 6.

Front

What are the properties of opposite angles in a parallelogram?

Back

The opposite angles of a parallelogram are congruent (equal in measure).

Front

Which quadrilaterals have four right angles?

Back

Only squares and rectangles have four right angles.

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.

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides equal and four right angles.

Front

What is a square?

Back

A square is a special type of rectangle where all four sides are equal in length.

Front

What is a rhombus's relationship to a square?

Back

A square is a specific type of rhombus where all angles are right angles.

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is found by multiplying its length by its width (Area = length × width).

Front

What is the formula for the area of a rhombus?

Back

The area of a rhombus can be calculated using the formula: Area = (d1 × d2) / 2, where d1 and d2 are the lengths of the diagonals.
