Draw a line of any length. Set the protractor at one end of this line and draw an angle of 60 degrees - measuring angles from the other end of the line. Move the protractor to the other end of the original line and repeat.
If necessary extend the lines of the angle until they meet. The three lines will form a regular (equilateral) triangle.

Is it possible to solve a right triangle without using Pythagorean theorem?
Yes simply with a protractor and a measuring device.
How do you find the value of an angle?
You could measure it using a protractor, derive it from basic geometric properties (for example angles of a regular polygon), or calculate it using trigonometry.
When given all 3 side lengths of a triangle but none of the angle measures you can solve for all angle measures using?
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
How do you find a 30 degree angle without a protractor?
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
How do you measure the internal angles of a triangle?
Using a protractor, you place the "elbow" of the triangle under "0"-- zero. Line up the big black like that is in the middle of the protractor- the straight part to one side. Using a pencil, place it right on top of the other side. Read the number on the curved edge. You should get a number no more than 90 degrees on any one angle. All angles of a triangle-3 angles.... equal 180 when they are added together.
What is the formula for finding the height of a triangle?
using a protractor
Pei Lin wants to construct a regular hexagon using a protractor what shows a protractor that is not placed correctly?

How do you make an angle without using compass and protractor?
By drawing regular polygons as for instance a square will have 4 equal right angles and an equilateral triangle will have 3 equal 60 degree angles.
How do you know that a triangle adds up to 180?
Using a protractor you'll find that the 3 angles of any triangle add up to 180 degrees
Is it possible to solve a right triangle without using Pythagorean theorem?
Yes simply with a protractor and a measuring device.
How do you use the measures of a triangle to show that a triangle is a right triangle?
Using a protractor which should give a measure of a 90 degree angle and two acute angles that add up to 90 degrees.
How do you draw a triangle without using a compass or ruler?
You can use a protractor! Draw the baseline and measure the angles and mark them. Then finally join them together!
How do you find the value of an angle?

How does someone measure angles?
You can onlymeasure angles by using a protractor.
How do you construct 120 degree angle without using a protractor?
Construct an equilateral triangle because each of its 3 exterior angles measures 120 degrees
