Step-by-step explanation:
Properties of a parallelogram
a. Opposite sides are parallel and congruent.
b. Opposite angles are congruent.
c. Adjacent angles are supplementary.
d. Diagonals bisect each other and each diagonal divides the parallelogram into two congruent triangles.
e. If one of the angles of a parallelogram is a right angle then all other angles are right and it becomes a rectangle.
The properties of the triangle are:
a. The sum of all the angles of a triangle(of all types) is equal to 180.
b. The sum of the length of the two sides of a triangle is greater than the length of the third side.
c. In the same way, the difference between the two sides of a triangle is less than the length of the third side.
d. The side opposite the greater angle is the longest side of all the three sides of a triangle.
e. The exterior angle of a triangle is always equal to the sum of the interior opposite angles. This property of a triangle is called an exterior angle property
f. Two triangles are said to be similar if their corresponding angles of both triangles are congruent and lengths of their sides are proportional.
