Online protractor or angle problems with acute, obtuse, reflex angles. For example, if you counted 20° from the dotted line, the reflex angle measures 180 + 20 which is 200°. Determine what type of angle you're measuring. This is how you can use a protractor to measure as well as draw angles, quickly and easily. The pdf file also has the answer sheet. To measure an angle properly, first you can use the straight edge of the protractor to make the lines longer on the angle. Trace along the inside of the T-bevel blade and handle. gastonma. An angle is formed when two lines intersect in a point. This app turn your iPhone into a handy pocket protractor that can measure angles in both degrees and radians. Using a protractor, swing the blade until the desired angle between the handle of the bevel and the blade matches the angle you want. Using a protractor, accurately sketch an angle with a given angle measurement. A compass helps to construct an angle.. Set squares, also known as triangle protractor, are used to draw parallel and perpendicular lines. How to use: Place the flat side of the protractor to lie on one of the lines of a given angle and make sure that the other line lies inside the protractor, then you can draw a line with your finger to help you measure the angle. How to measure an angle with a protractor: Place the midpoint of the protractor on the VERTEX of the angle. Lay the T-bevel on your working surface. This online practice module will help students learn to use a protractor to measure precise angle measures. If an angle is less than 90 degrees, it's an acute angle. If the lines of the angle measure are short like the picture below then to get an accurate measurement, extend the angle's line until it passes the protractor. Line up one side of the angle with the zero line of the protractor (where you see the number 0). Read from zero on the outer scale of your protractor. When measuring an angle, the center point should align with the center point of the protractor, and one arm or ray should align with the base of the protractor.
