What is the L shaped ruler called?
Hand squares are used to measure right angles. They have degrees from 0 to 360 and are usually L-shaped. As you figure out how to measure angles for the construction of stairs, frames and rafters, they are very useful.

The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.
Can you measure angles with a ruler?
The folding ruler is a common tool for measuring length, but it can also be used to measure these angles on the go. Home building and repair work often deals with angles. Plumbers and carpenters must work with and around these angles, even replacing pipes that must be bent at an angle to fit.
An angle ruler allows students to measure a drawn angle somewhat accurately.
