Let us now find out the **angle or slope** of the staircase as shown below.

**Type-1:**

If the riser & tread are known.

__Given data:__

Riser = 160mm.

Tread = 250mm.

Slope

= [riser ÷ tread]

= [ 160mm.÷ 250mm.]

= **0.64**

Here, slope = tanθ

So,

tanθ = 0.64

θ = tan-1 0.64

= **32.62°**

**2. Type-2**

If the height & horizontal distance of the staircase are known.

__Given data:__

Height of landing = 1300mm.

Horizontal distance = 2000mm.

tanθ = [opposite ÷ adjacent]

= [height ÷ horizontal distance]

= [ 1300mm.÷ 2000mm.]

= **0.65**

θ = tan-1 0.65

= **33.02°**
