Welcome to Catalytic, a blog to discuss the discussion of subject matter from Higher Education, High School, Middle School and Elementary Schools. This time, Katalistiwa will discuss a question that is often asked in school exams. The questions are: **The length of AB is**

**Detailed discussion of Length in Right Triangles**

Pytahoras theorem or theorem Pythagoras is a theorem on a triangle a right angle where the sum of the two sides of a triangle is equal to the square of the length of the hypotenuse or the hypotenuse.

For triangle ABC right angled at B then apply

- AB and BC are the sides of triangle ABC.
- AC as the slanted side or hypotenuse.
- Applies equality

or

or

In a right triangle, the hypotenuse is the longest side when compared to the lengths of the other sides. The three numbers that conform to the Pythagorean theorem are called Pythagorean triples. An example of a Pythagorean triple is:

- 3, 4, and 5 and their multiples.
- 5, 12, and 13 and their multiples.

**Explanation with steps:**

**Is known:**

- Triangle ABC is right at B.
- BC = 12 cm
- AC = 15 cm

**Asked:**

- AB?

**Answer:**

** = 9 cm**

**Question Details**

**Class : **VIII

**Course : **Mathematics

**Chapter : **Pythagorean theorem
