Not necessarily; a rhombus has 2 pairs of opposite sides which are parallel, like the parallelogram, and its diagonals are perpendicular. (It also has all its sides of the same length.)
the diagonal in a paralleogram is not equal but the diagonals in the rectangle are congruent this is because the opposite sides of a parallelogram and rectangle are same parallel to each other but the adjacent sides of a parallelogram is not perpendicular where as the adjacent sides of rectangle is perpendicular to each other.
Yes.
No.
There are four perpendicular lines in a rectangle
They are what makes it a rectangle. The rectangle is a special kind of parallelogram. The perpendicular lines cause it to be called a rectangle.
Yes. Squares, rectangles, and rhombera are special kinds of parallelograms.
It's a spelling mistake - the word is QUADRILATERAL and it means having four sides - like a square, rectangle, oblong, kite, diamond and such.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
The diagonals of a rectangle are never perpendicular but the diagonals of a square are perpendicular
The diagonals of a square are perpendicular whereas the diagonals of a rectangle are not perpendicular.
A rectangle has 4 perpendicular lines that meet at right angles.
The diagonals of a square are perpendicular whereas the diagonals of a rectangle are not perpendicular.
