If one pair of opposite angles of a quadrilateral is congruent then the quadrilateral is a parallelogram?
false; if both pairs
Is a quadrilateral a parallelogram if one pair of opposite angles is congruent and one pair of opposite sides is parallel?
Yes, it is.
If all four sides of a quadrilateral are congruent then is the quadrilateral a parallelogram?
Yes. It's definitely a parallelogram, and also definitely a rhombus. And if one of its angles happens to be 90 degrees, then it's also a square.
Does an isosceles trapezoid have one pair of congruent opposite sides and congruent base angles?
Yes, an isosceles trapezoid has one pair of congruent opposite sides and congruent base angles
If one pair of opposite sides of a quadrilateral is parallel and then the quadrilateral is a parallelogram?
Then, the opposite sides are congruent.
Explain one way to determine if a quadrilateral doesn't have congruent angles?
If its 4 sides are of different lengths then it will have no congruent angles
If one pair of opposite angles of a quadrilateral are congruent and one pair of opposite angles are congruent then is the quadrilateral a parallelogram?
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
If one pair of opposite angles of a quadrilateral is congruent then the quadrilateral is a parallelogram?
false; if both pairs
Is this statement true or falseIf one pair of opposite angles of a quadrilateral is congruent, then the quadrilateral is a parallelogram?
false
What quadrilateral must have exactly one pair of congruent angles?
A kite or arrowhead.
All of the angles of a quadrilateral are congruentcan the quadrilateral be a pallegram?
It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.
Is a quadrilateral a parallelogram if one pair of opposite angles is congruent and one pair of opposite sides is parallel?
Yes, it is.
Is this statement true or falseIf a quadrilateral is a trapezoid, then each pair of base angles is congruent?
A trapezoid is a quadrilateral with exactly ONE set of parallel sides
If one side of a quadrilateral is congruent to its opposite side then the quadrilateral is a parallelogram?
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.
What quadrilateral has all right angles and all sides congruent?
This is all about the vocabulary. First, quadrilateral, ok so a quadrilateral is a shape with four sides. Next, congruent; congruent basically means equal. So we can say what shape has four equal sides and right angles? Your basic shapes with four sides would be a trapezoid, a parallelogram, a rhombus, a rectangle or a square. The square is the only one of these that fits.
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)
Which of the following is not a sufficient condition for concluding a quadrilateral is a parallelogram?
at least one pair of opposite sides is parallel
