Step 1: Draw the Rhombus
The first step in finding the height of a rhombus is to draw the rhombus. You can either draw it on a piece of paper or visualize it in your mind. It is important to remember that a rhombus has four equal sides and two pairs of opposite angles that are equal.
Step 2: Label the Rhombus
To make the calculations easier, we need to label the rhombus. Start by choosing one side of the rhombus and label it as “a”. Next, draw a that bisects this side and label it as “d”. Label the height of the rhombus as “h”.
Step 3: Use the Pythagorean Theorem
The next step in finding the height of a rhombus is to use the Pythagorean Theorem. According to this theorem, in a right-angled triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In a rhombus, the diagonal, “d”, divides the rhombus into two right-angled triangles. Therefore, we can use the Pythagorean Theorem to find the length of the diagonal.
a² + b² = c²
Where a and b are the lengths of the two shorter sides and c is the length of the hypotenuse.
Since a rhombus has four equal sides, we can write
a² + a² = d²
Simplifying this equation, we get,
2a² = d²
Divide both sides by 2 to get
a² = (d²/2)
Step 4: Use the Formula for the Area of a Rhombus
The formula for the area of a rhombus is (diagonal x height)/2
Substituting the value of a² from step 3 into this formula, we get
Area = (d x h)/2
2a² = d²
Simplifying this to h = 2A/d
Step 5: Substitute the Given Values
The final step is to substitute the given values into the formula to find the height of the rhombus. For example, let’s say that the diagonal of a rhombus is 10 cm and its area is 40 cm². We can use these values in the formula to find the height of the rhombus.
h = 2A/d
h = 2 x 40/10
h = 8 cm
Therefore, the height of this rhombus is 8 cm.
