Explanation :

How many different types of triangles are there?

There are 6 types of triangles.

➝ Scalene Triangle➝ Isosceles Triangle➝ Equilateral Triangle➝ Acute Triangle➝ Obtuse Triangle➝ Right Triangle

$\begin{gathered}\end{gathered}$

Draw and name the 4 different triangles.

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

The name of four triangles are :

➝ Right angled triangle ➝ Isosceles triangle ➝ Equilateral triangle ➝ Scalene triangle

$\begin{gathered}\end{gathered}$

Write the properties of each triangle.

1. Acute-angled Triangle

$\pink\implies$ Each of the angles is below 90⁰, and the sum of those angles is always 180⁰.

2. Right-angled Triangle

$\pink\implies$ 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

$\pink\implies$ 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

$\pink\implies$ 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

$\pink\implies$ 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

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

$\begin{gathered}\end{gathered}$

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

$\green\implies$ 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:

➝ Centre➝ Radius➝ Diameter➝ Circumference➝ Tangent➝ Secant➝ Chord ➝ Arc➝ Segment➝ Sector

$\begin{gathered}\end{gathered}$

Find the relationship between radius and diameter.

$\pink\implies$ The relationship between radius and diameter is the diameter of a circle is twice of its radius.
