## Find the Crossing Angle – Problem & Solution

**Mathematical Problem:**

Find the crossing angle of 1 in crossing by using all the three methods(Right angle, centre line and isosceles triangle method):

**Solution:**

**1. By using right angle method**

We know, [N = = 8.5]

So, Angle of Crossing =

**2. By using centre line method**

We know,

So, Angle of Crossing =

**3. By using Isosceles triangle method**

We know,

Or,
