Point P will be the vertex of an angle QPO.į. Draw a point P on AB that is 4 cm from A.Į. Draw ray OC so that the ray is above AB and angle COB is 30°.ĭ. Point O will be the vertex of an angle COB.Ĭ. Draw a point O on AB that is 4 cm from B.ī. Draw a horizontal segment AB, 12 cm in length.Ī.Use your compass to construct two circles: Draw a segment AB with a length of your choice.Use your compass to find a point on your second segment, which will be labeled D, so that CD = AB. Draw a second segment that is longer than AB and label one endpoint C. Draw a segment AB that is 5 cm in length.Draw a rectangle ABCD so that AB = CD = 8 cm and BC = AD = 3 cm.Draw three adjacent angles a°, b°, and c° so that a = 25°, b = 90°, and c = 50°.Use your compass to draw three circles, each with a radius of one of the drawn segments. Draw three distinct segments of lengths 2 cm, 4 cm, and 6 cm. Label each angle formed with its measurement. Draw vertical angles so that one angle is 135°.Draw complementary angles so that one angle is 35°.Use your ruler to draw three segments of the following lengths: 4 cm, 7.2 cm, and 12.8 cm.Use a ruler, protractor, and compass to complete the following problems. Angle the compass relative to the paper holding the compass perpendicular to the paper will make it difficult to maneuver.Using one hand, place weight on the point of the compass and let the pencil-end be relatively loose.Adjust the compass to the intended radius length. Tips to drawing circles with a thumbscrew compass: The point where the needle of the compass sits represents the center of the circle and its radius can be adjusted by widening or narrowing the two arms of the compass. A compass can be used to construct circles, to measure and mark off a segment of equal length to another segment, and to confirm the fact that the radius of the center of a circle to the circle itself remains constant no matter where you are on the circle.Ī compass is a tool for drawing circles.Students use a compass, protractor, and ruler to draw geometric shapes based on given conditions.New York State Common Core Math Grade 7, Module 6, Lesson 6ĭownload worksheets for Grade 7, Module 6, Lesson 6 Lesson 6 Student Outcomes Examples, videos, and solutions to help Grade 7 students learn how to use a compass, protractor, and ruler to draw geometric shapes based on given conditions.
