If both pairs of opposite angles of a quadrilateral are congruent is the quadrilateral a parallelogram?
Yes
What are all the names of all the quadrilateral with pictures?
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.
If one pair of opposite angles of a quadrilateral is congruent then the quadrilateral is a parallelogram?
false; if both pairs
Conditions which guarantee that a quadrilateral is a parallelogram?
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
What is the difference between a rectangle and a diamond?
A rectangle is a quadrilateral with four sides. All angles are right angles, the diagonals are congruent, and the opposite sides are all equal. A rhombus (diamond) is a quadrilateral with congruent daigonals and equal 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 both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is not a parallelogram?
False. If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram.
What is a quadrilateral with all sides congruent and opposite angles congruent?
A square
Can congruent angles determine if there is a parallelogram?
If both pairs of opposite angles of a quadrilateral are congruent, then it is a parallelogram.
Opposite angles are congruent and supplementarybut the quadrilateral is not a rectangle?
no
What is a quadrilateral whose opposite sides are parallel and congruent and whose opposite angles are congruent?
its a shape
If both pairs of opposite angles of a quadrilateral are congruent is the quadrilateral a parallelogram?
Yes
If both pairs of opposite angles of a quadrilateral are congruent then the quadrilateral is a parallelogram?
True
Quadrilaterals are consecutive and opposite angles always congruent?
There are instances that quadrilateral angles can be consecutive and opposite angles are congruent. The best examples are square and rectangle.
What is a quadrilateral with 2 pairs of opposite congruent angles?
a parallelogram
What are all the names of all the quadrilateral with pictures?
