Properties of Parallelograms
Parallelograms are quadrilaterals with opposite sides parallel and equal in length. This property gives parallelograms several unique characteristics.
Properties of Parallelograms:
- Opposite sides are parallel and equal in length.
- Opposite angles are equal in measure.
- Consecutive angles are supplementary (add up to 180 degrees).
- Diagonals bisect each other.
Parallelogram defg
Given parallelogram defg, we have the following information:
- dh = x + 1
- hf = 3y
To find the length of side dh, we can use the fact that opposite sides of a parallelogram are equal in length:
dh = gf = x + 1
Therefore, the length of side dh is x + 1.
Triangle dfh, In parallelogram defg dh x 1 hf 3y
Triangle dfh is a right triangle because it satisfies the Pythagorean theorem:
dh2+ hf 2= df 2
Substituting the given values, we get:
(x + 1)2+ (3y) 2= df 2
Simplifying, we get:
x2+ 2x + 1 + 9y 2= df 2
Since df is the length of the diagonal of the parallelogram, we know that df 2= 2(dh 2) = 2((x + 1) 2).
Substituting this into the previous equation, we get:
x2+ 2x + 1 + 9y 2= 2(x 2+ 2x + 1)
Simplifying, we get:
x2+ 2x + 1 + 9y 2= 2x 2+ 4x + 2
Subtracting x 2+ 2x + 1 from both sides, we get:
y2= x 2+ 2x + 1
Therefore, the length of side hf is 3yand the measure of angle dhf is 90 degrees.
Area of Parallelogram defg: In Parallelogram Defg Dh X 1 Hf 3y
The area of a parallelogram is given by the formula:
Area = base × height
In this case, the base is dh = x + 1 and the height is hf = 3y.
Therefore, the area of parallelogram defg is:
Area = (x + 1) × 3y = 3xy + 3y
