What are some alternatives to using a protractor for measuring angles?

There are several alternatives to protractors, such as using a compass, a ruler with angle markings, or even digital angle finders.

Can you explain how to use a compass for measuring angles?

Sure! To use a compass, place the point on the vertex of the angle, then draw an arc that intersects both rays of the angle. Measure the angle using the markings on the compass.

What about using a smartphone app?

Yes, many smartphone apps can measure angles using the phone's built-in sensors. Just align the phone with the angle, and the app will display the measurement.

Are there any DIY methods to measure angles?

Absolutely! You can create a simple angle measuring tool using a piece of cardboard and a protractor template. Just cut out the angle and use it to compare.

Which method do you think is the most accurate?

Digital angle finders are generally the most accurate, but for quick measurements, a compass or smartphone app can be very effective.
