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
True or false:
There is only one right angle in rectangle.
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.
