- Definition: A parallelogram is a quadrilateral with both pairs of opposite sides parallel. *Parallelogram I have: - 2 sets of parallel sides - 2 sets of congruent sides-opposite angles congruent-consecutive angles supplementary-diagonals bisect each other-diagonals form 2 congruent triangles.

- 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 paral…lel 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.

SOLUTION: In a parallelogram ABCD, angle A = 70 degrees. Find the remaining angles. The sum of the angles of a parallelogram is 360 degrees. At least two angles will be the same unless one angle is of measure 90 degrees (in which case all four are 90). Hence, the remaining angles are 70 degrees and 2 110 degree angles.

Properties of Rectangles, Rhombuses, and Squares Parallelogram A is a rhombus. In Parallelogram B, we see that there are four right angles and that the pairs of opposite sides are congruent. However, consecutive sides are not congruent, so we can eliminate rhombuses and squares from our options. Thus, Parallelogram B is a rectangle.

Quadrilaterals A square has equal sides and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles a are the same, and angles b are the same).

Why is a rectangle always a parallelogram but a parallelogram is not always a rectangle? A parallelogram is a 4-sided shape where opposites sides are parallel. A rectangle is a special case of a parallelogram. All rectangles are parallelograms. But a rectangle is a shape where opposites sides are parallel *and* all the corners are 90 degree angles. So you can't say that all parallelograms would be rectangles. Some parallelograms would be rectangles, but not all. Rectangles are a subset of the shapes called parallelograms.

Parallelogram Parallelogram. A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle. parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.

Why is a square a parallelogram? A parallelogram is a rectangle with each side that it's opposite to (or doesn't intersect with), parallel to the other, meaning that if the lines just continue and continue, they'll never intersect. A square is a parallelogram because the opposite sides, if you continue the line, they'll never touch each other.

2-D and 3-D Figures, Polygons, and Quadrilaterals This is a parallelogram. A parallelogram has both pairs of opposite sides that are parallel. It has 4 sides and 4 vertices. 2 of its angles are more than 90 degrees or obtuse and 2 of its angles are less than 90 degrees, or acute.

Parallelogram Rectangles, rhombuses, and squares are all parallelograms. As shown in the picture on the right, because triangles ABE and CDE are congruent (have the same shape and size), In all Parallelogram's opposite angles are equal to each other. Angles which are not opposite in the Parallelogram will add up to 180 degrees.

Parallelogram 1 Opposite sides of a parallelogram are parallel (by definition) and so will never intersect. 2  The area of a parallelogram is twice the area of a triangle created by one of its diagonals.  The area of a parallelogram is also equal to the magnitude of the vector cross product of two adjacent sides.

- Use the ASA postulate to that $$ \triangle ACB \cong \triangle DCB $$. Use the ASA postulate to that $$ \triangle ABD \cong \triangle CBD $$. We can use the Angle Side Angle postulate to prove that the opposite sides and the opposite angles of a parallelogram are congruent. Given: ABCD is a parallelogram. Prove the opposite sides and the opposite angles of a parallelogram are congruent.

Does a Parallelogram Have a Right Angle? Some parallelograms, such as rectangles and squares, contain right angles. Another type of parallelogram, known as a rhombus, may or may not contain right angles. Quadrilaterals are closed, co-planar geometric shapes that comprise two diagonals and four sides, where all four interior angles have a sum of 360 degrees. Special types of quadrilaterals include parallelograms, rectangles, squares, rhombuses, trapezoids and kites. Parallelograms contain two pairs of opposing sides that are parallel and equally long. The opposite angles of parallelograms are also equal. Rectangles, squares and rhombuses are considered parallelograms because they share the same properties as a parallelogram. The four interior angles of rectangles and squares are all right angles, or 90-degree angles. The opposite angles, also called supplementary angles, have a sum of 180 degrees.

- What polygons are parallelograms? Every 4-sided polygon in which the opposite sides are parallel is a parallelogram. Opposite sides are equal too, but it's not necessary to make that an explicit requirement,… because if both pairs of opposite sides are parallel, then they also wind up being equal.

- A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. An additional property of a parallelogram is that both pairs of opposite sides are congruent. Note: Similar arrow markings indicate that the sides are parallel.

Parallelogram Also, side AB is equal in length to side DC, since opposite sides of a parallelogram are equal in length. Therefore triangles ABE and CDE are congruent (ASA postulate, two corresponding angles and the included side).

- 1 An equivalent condition is that opposite sides are parallel (a square is a parallelogram), that the diagonals perpendicularly bisect each other, and are of equal length. 2  A quadrilateral is a square if and only if it is both a rhombus and a rectangle (four equal sides and four equal angles). Rectangle: all four angles are right angles. 2  An equivalent condition is that the diagonals bisect each other and are equal in length. 3  Informally: a box or oblong (including a square). 4  Square (regular quadrilateral): all four sides are of equal length (equilateral), and all four angles are right angles.
