Unit 2 ConstructionsOnline version Use the video of geometric constructions to answer the questions. by Holly Davis 1 Why does he use the same size circle to copy an angle? a Because he is lazy. b Because the reference circles need to be the same size. c Because he likes all the circles to be the same. 2 Why are the two arcs exactly the same? a They look the same. b They are not the same. c They are the same distance apart. 3 What do you know about an angle and its copy? Written answer 4 Where do you place the brass ring, or center, of your compass? a On the first ray b On the second ray c On the vertex d On the arrow 5 Where should the two congruent arcs intersect? a In the exterior of the angle b In the interior of the angle c On a side of the angle d At the vertex of the angle 6 How are the "top angle" and the "bottom angle" related to each other? a They are congruent b The top is smaller than the bottom c The bottom is smaller than the top d They are not related 7 What figure is an angle bisector? a Line b Segment c Ray d Angle e Point 8 Why does the dot chosen need to be over halfway across the segment? Written answer 9 What is also constructed when bisecting a segment? a Circles b Midpoint c Endpoint d Lines e Point 10 What is a third figure constructed using this method? a Parallel Lines b Transversal c Perpendicular Bisector d Obtuse Angles e Point Explanation 1 Think about properties of circles. 2 He mentioned the answer earlier in the clip. 3 How are they related? 4 Look at the steps for your constructions. 5 Think about where the angle bisector needs to be. 6 What does bisect mean? 7 What figure did he draw last? 8 Think about what is coming next... 9 Think about what is coming next... 10 Think about what is coming next...
