Which component is referred to as the riser in a staircase?

The vertical part between two treads
The horizontal part that you step on
The angled support for the stairs
The overall height of the stairs

The correct answer is: The vertical part between two treads

The riser in a staircase is defined as the vertical component that exists between two treads. Treads are the flat horizontal surfaces that you step on while risers are positioned upright to support them, forming the height of each step. This configuration is essential in defining the staircase's overall structure and usability because it determines both the rise and run of the stairs, impacting its overall slope and safety. A staircase's proper construction involves maintaining consistent riser heights to ensure comfortable and secure navigation up and down the stairs. Understanding this terminology is crucial for carpentry work related to stair construction, helping carpenters accurately design and build safe and functional staircases.
