class=\"wp-block-list\">\n<li>Place the vertex of the angle at the center of a protractor.<\/li>\n\n\n\n<li>Align one of the angle&#8217;s rays with the baseline of the protractor.<\/li>\n\n\n\n<li>Read the angle measurement where the other ray intersects the protractor scale.<\/li>\n\n\n\n<li>Ensure the protractor&#8217;s zero mark aligns with one ray for accurate measurement.<\/li>\n<\/ul>\n\n\n\n<p>A protractor can be used to construct and measure the angle.<\/p>\n\n\n\n<p>Suppose we have to measure the angle given below.&nbsp;<\/p>\n\n\n\n<figure
