How To Use A Protractor To Measure And Draw Angles Explained From The In this video we discuss how to use a protractor to measure and draw angles. we go through examples using the left and right side of the protractor to measu. Try to measure the angles a, b and c inside the triangle. drag the protractor and rotate it using arrow keys. be careful which angle you read from the protractor. hint: if you get them all correct, they will add up to 180°.
How To Measure Angles With A Protractor I explain what an angle measure is, how to measure angles with a protractor, and how to draw angles with a protractor.when an angle "opens", it draws an arc. 1. draw a straight, horizontal line. use a ruler or the straight edge of your protractor to draw your reference line, or the first ray of your angle. make this line horizontal and any length you like. [6] the length of the line doesn’t matter. 2. place the hole or vertical line on your protractor at 1 end of the line. Welcome to how to use a protractor with mr. j! need help with using a protractor to measure angles? you're in the right place!whether you're just starting ou. A protractor can be used to measure and draw angles. the following steps can be used to draw angles using a protractor. for example, let us draw ∠ cob = 50°. step 1: draw a baseline ob. step 2: mark the point o and place the center of the protractor at o. step 3: align the baseline of the protractor with the line ob.

A protractor can be used to measure and draw angles. the following steps can be used to draw angles using a protractor. for example, let us draw ∠ cob = 50°. step 1: draw a baseline ob. step 2: mark the point o and place the center of the protractor at o. step 3: align the baseline of the protractor with the line ob. First, make sure that you correctly identify the angle in question. ∠mln is the angle formed by points m, l, and n with a vertex at point l. notice that the ∠mln is now colored in the diagram below. if you find having the angle colored helpful, you can use markers or highlighters whenever you are using a protractor to measure angles on paper. A reflex angle is the "outside" of an acute or obtuse angle. use the protractor to read the measure of the "inside" of the angle. then subtract from 360 to get the measure of the reflex angle. if the inside is the same obtuse angle we just measured, then the measure of the outside is. 360 135 = 225 degrees.
