(\u00b0) using a<a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/geometry\/protractor\"> protractor.<\/a> A protractor is a measuring device that is used to calculate or draw angles in terms of degrees.<\/p>\n\n\n\n<p class=\"eplus-wrapper\">For example, in the image below, we see that using a protractor, the black arrow points to 100\u00b0, crossing 90\u00b0. Hence, the measure of the angle is 100\u00b0.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"346\"
