Step 1:
I'll solve this problem step by step using precise geometric construction techniques:

Step 2:
: Understand the Angle Construction

- We want to create an angle that is $$135^{\circ}
To draw a 135 -degree angle, we'll use a systematic approach that breaks this into manageable geometric steps:

Step 3:
: Angle Decomposition Strategy

- Add an additional $$45^{\circ}$$ to reach $$135^{\circ}
- Start with a right angle (90^{\circ})

Step 4:
: Construction Method

Step 5:

Draw a horizontal line segment as the first ray

Step 6:

Use a protractor or compass to construct a $$90^{\circ}$$ angle

Step 7:

From the $$90^{\circ}$$ line, rotate an additional $$45^{\circ}$$ to create the second ray

Step 8:
: Verification

- Total angle between rays: $$90^{\circ} + 45^{\circ} = 135^{\circ}
- First ray: Horizontal line

Final Answer

A 135 -degree angle can be accurately drawn by first creating a right angle and then rotating an additional 45 degrees from the original ray.
