The intersection of two lines is a ________. 4. The intersection of two planes is a _______. 5. If two points lie on a plane, then the line containing them _______________. 1. 2. 3. 4. Name the intersection of line n and segment AI. Name the intersection of planes Q and MPT. Name three coplanar points in the figure. Name plane Q another way. Show how the following are written by providing an example: Point 2. Line 3. Plane 4. Ray 5. Segment 6. Angle 1. Line CD is the perpendicular bisector of segment AB . If AM = 14, find AB. Points Y, G, and B are located on a straight line. B is between Y and G. If YB is 6 less 4 times the length of BG, and YG = 34, find YB. Find the length of the segment from -1782 to 577. State the definitions of the following: Acute angle Obtuse angle Reflex angle Right angle Straight angle Describe the relationship between angles a and b. 1. 2. The intersection point of the angle bisectors of the angles of a triangle is the center of the ____________________________ circle of the triangle. The intersection point of the perpendicular bisectors of the sides of a triangle is the center of the ______________________________ circle of the triangle. Explain how the following diagram was created. What are the special lines that run through the vertex to the midpoint of the opposite side of a triangle called? [not on the test] Draw the segment that represents the distance from the point to the line. Draw the perpendicular bisector of the segment below. 1. 2. Draw the angle bisector of the angle below. Place point C in the INTERIOR of the angle. Name all congruent segments. E F A B C D If m∠XAC = 14x – 10 and m∠BAX = 46°, find x. Use the rule T(x,y) = (-x , y) to transform the figure in the coordinate plane at the right. Identify the transformation shown below. Describe the transformation that results after applying the rule T(x,y) = (x – 4, -y) to a figure in the coordinate plane. Use the rule T(x,y) = (x – 2, y + 1) to transform the figure in the coordinate plane. Label your image.
