How many different types of triangles are there?

There are 6 types of triangles.

Draw and name the 4 different triangles.

The diagram of 4 different triangles is in the given pic. So, please check out the attachment.

The name of four triangles are :

Write the properties of each triangle.

1. Acute-angled Triangle

Each of the angles is below 90⁰, and the sum of those angles is always 180⁰. 

2. Right-angled Triangle

One side being 90⁰, the other angles have to be acute. It is because the addition of all internal angles always produce 180⁰. 

3. Obtuse-angled Triangle

Naturally, the other two angles have to be smaller than an obtuse angle. It is so that the internal sum of all the angles remains 180⁰.

4. Equilateral Triangle

Since the internal angles add up to 180⁰, each angle has to be equal in an equilateral triangle. In this case, each angle of this triangle is 60⁰.

5. Isosceles Triangle

Since two sides have the same length, the third side has to have a different length. On top of that, the angle of the other side is also dissimilar to the previous angles. 

6. Scalene Triangle

In this case, the lengths of the three sides are diverse. However, the sum of dissimilar internal angles also has to be 180⁰. 

Draw a circle and name the different parts of the circle.

The diagram of circle is in the given pic. So, please check out the attachment.

Parts of circle :

A circle can have different parts and based on the position and shape, these can be named as follows:

Find the relationship between radius and diameter.

The relationship between radius and diameter is the diameter of a circle is twice of its radius.
