Answer 1

The vertical part of a stair step is called a riser.

Step-by-step explanation:

In a stair system, the vertical part of the step is called a riser. The riser is the portion of the step that you step up or down to go from one level to the next.

This step's horizontal portion is referred to as the "tread." In a staircase, the tread and riser come together to make a single step. In order to enable a secure and comfortable ascent or descent, stairs are constructed using a combination of risers and treads.

The vertical portion of a step in a stair system is referred to as a "riser." The vertical section between each tread (the step's horizontal portion) is called the riser. In a staircase, the tread and riser come together to form a single step.
