How To: Use Heron's formula

Area of a triangle can be calculated when you have the length of its base and height. In this case the area is 1/2 times the base and its height. If you do not know the height of the triangle but know the lengths of all the sides of the triangle then you can calculate its area using the Herons formula. First to use it you need to computer the semi perimeter of the triangle S, which is S = (a + b + c)/2, where a, b, c are the lengths of the sides of the triangle. Now the area of the triangle i...

How To: Find the area of a rhombus

In this video the tutor shows how to calculate the area of a rhombus. He gives the formula for the area of a rhombus as area a = ( D * d ) / 2 where D is the length of the longer diagonal and d is the length of the shorter diagonal. He shows how to solve such problems by taking an example of rhombus with lengths of longer and shorted diagonal and computes its area by substituting the values in the area formula. This video shows how to compute the area of a rhombus when the lengths of its long...

How To: Use the Pythagorean theorem

Pythagoras was a smart man, so smart that his mathematical theory is named after him and still used today, more than 2,000 years later: the Pythagorean theorem. It implies that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. The Pythagorean theorem is a cornerstone of geometry. Here’s how to use it.

This is a basic formula that you will use to find the arc length. When you plug in your values to this equation, you will find the answer. Practice with the example...

How To: Find the length of a segment using the midpoint II

First of all in the given question you have to write down the values of the total length of the line segment, PS=15. The length of the line segment, QR =3. Now you have to find the value of line segment RS. Because you know that the Q is the midpoint of the line segments PQ and QS must be equal. Therefore you can find out the length of the half of the segment using the midpoint. Subtract the value of QR from QS. Given that segment PS=15 and Q is the midpoint, you can conclude segment PQ=7.5 a...

How To: Find the perimeter of a shape

Two dimensional objects are measured in terms of perimeter and areas. A perimeter of a two dimensional object is the distance around that object. If you want to find the perimeter of an object, all you need to do is add up each one of the lengths of sides of that object. If you have a small figure like triangle, first compute the length of the three sides. Now adding these three sides gives you the perimeter of the triangle. A larger or more complicated shape might have more number of sides. ...
