This lesson may help you in the tricky math question we sent!
Hello everyone. Now we are going to discuss on a topic called the 'Pythagorean theorem'. The Pythagorean theorem is also known as 'Pythagoreanism'. Now you may know it. The famous Pythagorean theorem was founded by the famous philosopher, Pythagoras. Pythagorean theorem helps mathematics specially in geometry. Its easy to learn. There is a special thing we have to know. The Pythagorean formula/theorem can only be used when solving problems regarding a right-angled triangle. It mean, the theorem only solve problems which associates right-angled triangles. The function of Pythagoreanism is; can find the hypotenuse with the help of the perpendicular and the base. Don't be afraid of these words because from now, we are going to learn about it. Pythagoreanism is a formula like this.
Now let's see the perpendicular, base and the hypotenuse of a triangle and the letters used through a picture.
So the according to the figure you can identify it. The hypotenuse is the longest side of the triangle. It is indicated by 'c'. You can easily identify it because it is located opposite to the right angle. The base is identified by 'b'. The next one; the perpendicular. Perpendicular is indicated by 'a' and it is located perpendicular to the right angle. So these terms are also known as the Pythagorean triples. Now let's solve questions.
Question 1- The perpendicular the triangle is 3cm and the base is 4cm of a right-angled triangle. Find the value of the hypotenuse.
We can use the Pythagorean formula to find the base or the perpendicular when the hypotenuse and the base or the perpendicular is given.
Question 2- The hypotenuse is 10cm and the perpendicular is 6cm of a right-angled triangle. Find the length of the base.
Question 2- The hypotenuse is 10cm and the perpendicular is 6cm of a right-angled triangle. Find the length of the base.
So, now you may have an idea on the Pythagorean theorem introduced by Greek philosopher Pythagoras. The lesson is over. Be with us and we are going to upload more lessons on different subjects.
