Yes it's true.
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
True
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
All rectangles are parallelograms.
not true
True
yes. rectangles are just the special cases of parallelograms where the angles are all 900
False! Squares are parallelograms. Parallelograms can be squares or rectangles or neither.
No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Yes. All rectangles are also parallelograms, but not all parallelograms are rectangles.
True
True. All rectangles are parallelograms because they have opposite sides that are equal and parallel, and their angles are all right angles. This satisfies the definitions of both shapes, making every rectangle a specific type of parallelogram. However, not all parallelograms are rectangles, as parallelograms can have angles that are not right angles.
