Does a parallelogram always have four sides?
Yes, and its opposite sides are always equal and its opposite angles are always equal. The angles and the sides can be any size.
How can you tell if it is a parallelogram?
A parallelogram is a quadrilateral (four-sided figure) in which both pairs of opposite sides are parallel. You can check for that, specifically. As an alternative, you can check for any of the following conditions: * Opposite angles are congruent * Opposite sides are congruent
How do you describe the angles and sides of each quadrilateral?
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
Does a parelleogram have any symmetrical sides?
Yes, a parallelogram has 2 pairs of symmetrical sides. A rectangle is an example of a parallelogram but with all of its angles being 90 degrees whereas in a typical parallelogram none of the angles are 90 degrees. Opposite sides will be of equal lengths.
How many angles must measure 90 degrees in a parallelogram?
It is not a requirement that any of the angles are right angles (90 degrees), to qualify as a parallelogram.
A parallelogram that is not a square?
A parallelogram that is not a square is any parallelogram whose angles are not ninety degrees or whose opposite sides are not equal.
What angles does a parallelogram have?
It has 2 opposite equal acute angles and 2 opposite equal obtuse angles and the 4 angles add up to 360 degrees.
Does a parallelogram always have four sides?
Yes, and its opposite sides are always equal and its opposite angles are always equal. The angles and the sides can be any size.
Are all angles of a parallelogram congruent?
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
What quadrangle as equal opposite angles but not right angles and opposite side are parallel and equal in length?
Any parallelogram, including rhombus, but not including rectangle or square.
Are the opposite angles of any parallelograms are supplementary?
Yes, when they are both 90o and the parallelogram is usually referred to as a rectangle.
In what would Opposite angles are always congruent in what?
A parallelogram, or any regular n-gon where n is even.
What is a parallelogram with one interior angle equal to 90?
It is a square, a regular parallelogram with all right angles. The reason is that in a parallelogram, the adjacent angles are supplementary (equal 180 degrees).In any case, the opposite angle would be 90 degrees as well, leaving just 180 degrees for the other two identical opposite angles.
How can you tell if it is a parallelogram?
A parallelogram is a quadrilateral (four-sided figure) in which both pairs of opposite sides are parallel. You can check for that, specifically. As an alternative, you can check for any of the following conditions: * Opposite angles are congruent * Opposite sides are congruent
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
How do you describe the angles and sides of each quadrilateral?
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
