Before protractors were commonly used, people often relied on simple tools like straightedges, compasses, and right-angle rulers to measure angles. Additionally, they might have used the method of triangulation or geometric constructions to estimate angles in various applications. In some cases, they utilized basic geometric principles and visual estimation to achieve similar results in drawings and measurements.
What else can I help you with?
What do you use protractors for?
You use protractors to measure angles. There is a ruler on the flat edge of most protractors, too. It's very handy!
Why do you use protractors?
It depends on the type of protractor
How many protractors are they?
The number of protractors varies widely depending on the context—such as in a classroom, a school, or a specific educational setting. Typically, classrooms will have several protractors available for student use, while schools may have multiple sets. If you are referring to a specific location or context, please provide more details for a precise answer.
What instrument measures angle and length?
Protractors
Why are protractors in the shape of a semi circle?
usually they r semi-circular because mostly ques in exams are based on angles between 0 and 180 .But also there are 360 degree protractors but they r usually used by architectures.

MrSalvi bought 181 protractors to use with his classesIf he has 5classes with 31 students in each how many protractors does he have for each classes Explain your answer?
I'm not sure we should be doing your math homework for you, but if he divides up the protractors evenly among all five classes, he has 36 for four classes and 35 for the last one. 181 / 5 = 36.2
Do protractors have to be circles or half circles?
Protractors have to be half- circles because they measure angles less than 360 degrees.
What are the scapular protractors?
The scapular protractors are muscles that move the shoulder blades outward and forward. The main scapular protractors include the serratus anterior and the pectoralis minor. These muscles play an important role in stabilizing the scapula during arm movements.
