True or false?
One of the angles in a rectangle may be an acute angle.
One of the properties of a rectangle is that all its angles are right angles.
Therefore, it is not possible for an angle to be acute, that is, less than 90 degrees.
False
Look at the angles shown in the figure below.
What is their relationship?
\( \)
A rectangle has four right angles (90°) and opposite sides that are parallel and equal. This is what makes it special - no other quadrilateral has all four angles exactly 90°!
No, never! If even one angle is less than 90° (acute), then the shape is not a rectangle. It might be a parallelogram or another quadrilateral, but not a rectangle.
Rectangles only have right angles!
This is true for all quadrilaterals! Since rectangles have four 90° angles: 90° + 90° + 90° + 90° = 360°. This confirms our rectangle is correct.
Absolutely not! The moment you have an acute angle (less than 90°), the shape cannot be a rectangle by definition. It's a different type of quadrilateral.
