Because opposite angles are 90 degrees.
No. You cannot conclude anything about a shape which is not visible.

Zero.
A rhombus is a parallelogram because it has 2 sets of parallel sides.
A parallelogram is identified as a rectangle if it has four right angles (90 degrees). Additionally, the diagonals of a rectangle are equal in length and bisect each other. If you can confirm that either of these conditions holds true in a parallelogram, you can conclude that it is a rectangle.
Probably not since, as spelled, neither object exists. But a parallelogram is a polygon.
The dimensions of a rectangle are expressed as the extents of its sides in two orthogonal directions which are parallel to the sides. The lengths are usually unequal because otherwise the rectangle would be better known as a square.
The converse of the rectangle diagonal conjecture states that if the diagonals of a quadrilateral are equal in length, then the quadrilateral is a rectangle, which implies that its corners are right angles. To test if the corners of a quadrilateral are right angles, measure the lengths of the diagonals. If the diagonals are equal, you can conclude that the corners are right angles, confirming that the shape is a rectangle.
Since by definition a parallelogram is a quadrilateral with two sets of parallel lines, a rectangle is a parallelogram. Since we know that squares are rectangles, we can conclude that squares are parallelograms.
We conclude that the study is correct.I conclude an alliance.
Conclude your foolish computer game fast, and get back to studying. I will conclude my message. Every science project has a section to conclude it. Conclude is to end something. She did a short recap to conclude her speech.
I conclude that it is possible to make a sentence with the word "conclude."
