To draw the quadrilateral, start by drawing a straight line segment of 3 centimeters. This will be one of the sides of the quadrilateral.
Next, using the protractor, measure an angle of 80° at one end of the 3 centimeter side. From the vertex of this angle, draw another line segment of 3 centimeters.
Then, measure an angle of 85° at the other end of the second 3 centimeter side. From the vertex of this angle, draw another line segment of 3 centimeters.
Now, you have a quadrilateral with three sides measuring 3 centimeters each and two angles of 80° and 85°. To find the length of the fourth side, measure the distance between the endpoints of the two 3 centimeter sides. This measurement should be approximately 2.2 cm, which is the correct answer. Response 2 is correct.
Use a protractor to draw a quadrilateral so that three of its four sides measure 3 centimeters each. The angles between these sides have measures of 80° and 85°.
