The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure, while the sum of adjacent angles of a parallelogram is equal to 180 degrees. Before moving into the parallelogram formula let's have a look into its properties....
The base and the height of the triangle must be perpendicular to one another.Triangles and Rectangles A triangle is a polygon with three straight sides and three angles. Examples of triangles include the sail on a boat, a yield traffic sign or a sandwich cut diagonally. Some tortilla chips ...

Example 1:Parallelogram ABCD is made up of two triangles ΔABC and ΔACD. It is given that ∠ABC is 70° and ∠BCA is 30°, which are equal to ∠CDA and ∠DAC respectively. Side BC is equal to side AD. Can you tell which property is used to tell whether ΔABC and ΔACD are ...
A parallelogram is a 2-dimensional shape that has four sides and has two pairs of parallel lines. The parallelogram consist of equal opposite sides and its opposite angles are equal in measure. Let us now discuss the parallelogram formula i.e. area and p

a. Their angles are 60 degrees, so the angles in the hexagon are 120 degrees. The triangles can be extended below the hexagon to form a parallelogram of sides 2a. A larger triangle can be created to determine the height of this parallelogram, which is 2a — cos 30° = a — sqrt(3)...
