Place the midpoint mark of the protractor over the vertex C of the angle ACB. A protractor is a simple yet fundamental tool in a geometry box that is used to measure and draw angles in degrees. Click to set all the values to random values. Change this number to add or remove lines/angles to the current problem Toggle to show/hide the type of angle currently displayed. Select the mode, each option is a different angle type. The interactive clock angles activity can also be used in explaining angles. Using the vertically opposite rule, or spotting the supplementary angles.Īngles Glossary Acute Angle Any angle that is less than 90° Right Angle An angle that is 90° Obtuse Angle An angle greater than 90° but less than 180° Straight Angle An angle of 180° which makes a straight line Reflex Angle An angle greater than 180° Related activities Make a mark in the exact center of your line at 2.5 inches from the ends of the line. You can also use the bottom edge of your paper as the bottom edge of the protractor to skip this step. Notice that only one angle is given and all the other 3 can be worked out Draw a line on a piece of paper that is 5 inches long. The final mode deals with angles produced by an intersection of two lines. Problem followed by small adjustments to the lines by dragging. In this mode press =īutton to make all the angles equal. Mode behaves exactly the same as the previous. Supplementary angles are angles that add up to 180°. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Lo and behold the line went very close to a church marked on the map that was actually 4.14 miles away (The church was St. Such problems by selecting calculate from angles display, now press dice for a new Perfect school stationery for students and teachers. Missing angle that needs to be calculated. In this mode a complementary angle is shown, complementaryĪngles add up to 90° Initially the 90° is split by just one lineīut this can be changed by selecting a different number of lines. Types definitions are listed in the glossary below. So now you can change the angle by dragging a handle or clicking Click the angle type ctrl to either show or hide the Is great for identifying various types of angles. The initial mode is unique in that there is only one angle. The handles at the end of each line can be clicked and dragged Hidden the angle value next to the angle arc is replaced by the In all the modes individual angles can be shown or hidden for exampleĬlick the angle (a). Use the angles display to choose whether.The mode control is used to it selects the type of angle problem.
