Parallelograms: In geometry, a parallelogram is a two-dimensional four-sided shape, such that opposite sides have the same length and are parallel, and opposite angles have the same measure. D. Diagonals are congruent. Hence, opposite angles are bisected by the diagonals is not true for a parallelogram. $$\triangle ACD\cong \triangle ABC$$ If we have a parallelogram where all sides are congruent then we have what is called a rhombus. It has two pairs of equal angles. A Saccheri quadrilateral is similar to a trapezoid in the hyperbolic plane, with two adjacent right angles, while it is a rectangle in the Euclidean plane. Correct answers: 1 question: Which statement is true about parallelograms? Also opposite angles are equal (angles "A" are the same, and angles "B" are the same). A. Which statement is not always true about a parallelogram? 4) The opposite sides are parallel. This is sometimes true. The fact that forces happen to combine to form a parallelogram does not seem to be a mathematical law about how vectors are defined, but a peculiar empirical fact about the world we live in. These facts and properties are true for parallelograms and the descendant shapes: square, rectangle and rhombus. The properties of parallelograms can be applied on rhombi. Consecutive angles are supplementary C. Opposite sides are congruent. Each diagonal of a parallelogram separates it into two congruent triangles. One of the examples has its height drawn outside the parallelogram at a 90-degree angle to its base. C. The diagonals are congruent. This is always true. Characterizations.
