Triangles

When we say that two figures are similar, it means that they are of the same shape but not necessarily of the same size. In this topic, we will learn of the conditions under which two figures can be similar.

In this topic, we will learn the conditions under which two triangles can be similar. We will also learn about Thales Theorem, which was named after the famous Greek mathematician Thales.

In this topic, we shall make use of the theorem discussed in earlier sections to derive some criteria for similar triangles.

In this topic, we will earn to calculate the area of similar triangles with the help of theorems.

In this topic, we will prove the Pythagoras theorem using the concept of similarity of triangles. We will also learn new theorems that are used to solve problems.

This topic introduces the angle bisector of a triangle as a line that divides the angle of a side of a triangle into two segments that are proportional to each other. It uses examples and exercises to explain the concept.
