Find the **angle** of** Triangle, Equilateral Triangle, Right Triangle, Quadrilaterals**

In Geometry, every structure has particular dimensions like length of the side, angle etc. These dimensions create patterns and relationships which in fact gives us more information about a particular geometric figure. Let the geometric structure be any shape like a triangle or a quadrilateral, below are some of the rules shown.

**Equilateral triangle:** All sides and angles are equal. So let each angle be x°, then applying the above formula we get,

** **

**Right triangle: **In a right triangle, Pythagorean Theorem is usually used in order to find their respective sides.

**Example:** In a right triangle ABC, find the hypotenuse AC given AB=3, BC=5.

According to Pythagorean Theorem,

** AB ^{2}+BC^{2}=AC^{2}**

So, 3^{2}+4^{2 }= AC^{2}

**->** AC^{2} = 25 **->** AC=√25

** AC=5**

**Quadrilaterals: **

**Example: **Given a square, what is the measure of each angle?

Since all the angles in a square are equal,

** **** x+x+x+x=360**°

**->** 4x=360° **->** x = 360°/4

** -> x=90°**
