Triangles

This topic deals with the triangles. It shows the vertices, sides and angles of a triangle. We will learn about scalene, isosceles and equilateral triangles. It also explains the acute, obtuse and right triangles with the aid of figures.

This topic explains the characteristics of equilaterals and isosceles triangles. We will learn how the angles and sides differ in sizes when it comes to both the triangles.

This topic highlights the properties related to sides and angles of triangles. We will also discuss the sum of all interior angles of angles. Moreover, it talks about the angles of scalene and equilateral triangles.

From this topic, we will talk about right angled triangles in detail.. We will study the concept that is used in the theorem . We will also learn the definition of pythagoras theorem along with its formula.

The topic elaborates on the construction of triangles. The exterior angle of a triangle is equal in measure to the sum of interior opposite angles. The total measure of the three angles of a triangle is 180 degrees.

Through this topic, we will discuss the congruence of objects. It comprises the meaning of similar. We will learn various figures which have different shapes and sizes. We will understand the concept of congruent triangle in brief.

This topic covers the criteria for congruence of triangles. The congruence criteria for the triangles are SSS (Side-Side-Side) criteria, SAS criteria, and ASA Criteria.

Within this topic, we will understand the construction of circumcircle and incircle. We will learn their construction with the help of various steps. We will discuss some problems related to this concept.
