Protractor In Elementary Math At William Johnson Blog Step 1: place the center point of the protractor on the angle's vertex. there is an open hole at the bottom of the protractor and that is where you place the protractor onto the paper. the angle's vertex is where the two ray's meet. step 2: align the protractor with the bottom ray. step 3: read the angle's measure by finding where the top ray. A protractor is a handy tool used to measure and draw angles. there are different types, but the most popular ones are the semicircular and. the video below explains. protractor in elementary math. from newssow . printable protractor download protractor in elementary math a protractor is a simple measuring instrument that is used to measure.
Protractor In Elementary Math At William Johnson Blog 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°. 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. Kyoodoz presents: measuring angles with a protractor | elementary math. this video teaches students how to measure angles with the help of a protractor. teac. Drawing an angle. you may also use a protractor to draw an angle. begin by drawing a straight line using a ruler, and then line your protractor up with this line. one end of the line should be at the center of the circle drawn on the protractor. starting from zero, move up the curve of the protractor until you reach the desired number of.

An obtuse angle; 127°. a right angle; 90°. how to measure an angle with a protractor: place the midpoint of the protractor on the vertex of the angle. line up one side of the angle with the zero line of the protractor (where you see the number 0). read the degrees where the other side crosses the number scale. 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.
