Rectangle Properties

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with opposite sides that are equal in length and four right angles (90 degrees).

Front

What are the properties of opposite sides in a rectangle?

Back

Opposite sides of a rectangle are parallel and congruent (equal in length).

Front

What is the measurement of each angle in a rectangle?

Back

Each angle in a rectangle measures 90 degrees.

Front

Are all sides of a rectangle congruent?

Back

No, only opposite sides are congruent; consecutive sides are not necessarily equal.

Front

What is the relationship between consecutive sides in a rectangle?

Back

Consecutive sides of a rectangle are perpendicular to each other.

Front

If AB = 14 and BC = 9 in rectangle ABCD, what is the length of AD?

Back

AD = 14 (since opposite sides are equal).

Front

In rectangle ABCD, if AC is the diagonal, how can you find its length?

Back

Use the Pythagorean theorem: AC = √(AB² + BC²).

Front

What does it mean for angles in a rectangle to be congruent?

Back

It means all angles in a rectangle are equal in measure, specifically 90 degrees.

Front

Is it true that the diagonals of a rectangle bisect each other?

Back

Yes, the diagonals of a rectangle bisect each other and are equal in length.

Front

If the length of a rectangle is doubled, what happens to the area?

Back

The area of the rectangle is doubled if the length is doubled, assuming the width remains the same.
