Which picture shows a line that is the angle bisector? Definition: Angle bisector is the line that passess through the vertex of an angle divides thatangle into two equal angles. A) B) Definition: Perpendicular bisector is the line that passess through the midpoint of a segment at a 90 degree angle. Which picture shows a line that is the perpendicular bisector? A) B) C) Which term best describes line n? A n angle bisector perpendicular bisector right angle bisector D Fact: All points on the perpendicular bisector of a segmentare the SAME DISTANCE to the endpoints of a segment. Which of the following statements are true? A C B n D CD > AD AD = BD CA = CD CD = AB AD = Observe the diagram and its markings. Find the length of each of the following segments. If you can't find its length then type NA in the box. AB = CD = A 6.5 C B n 3.8 D Angle Bisector perpendicular midpoint perpendicular bisector Which term best describes ray LJ? Fact: Any point on an angle bisector is the SAME DISTANCE to the sides of the angle. Given the following diagram, what must LK measure? LK = 6.8 3.6 62o 62o A X Y Given the following diagram what can you conclude? Z AZ ≅ YZ ∆YXZ ≅ ∆AXZ all of the above Triangles ≅ by SSS or HL Given the following diagram and the fact that ∡HJK = 126o find the m∡LJK m∡LJK = o 3.6 3.6 Given the following diagram and the fact that ∡LJK = (4x - 14)o and m∡LJK = (3x + 6)ofind the value of xand the m∡HJK m∡HJK = o 3.6 3.6 Given the image. What can you conclude about the ∆ABC and ∆DBC? c. They are both right triangles b. They are congruent d. Both b. and c. are correct a. They are not congruent A C B n D 6.1 A X Y Given that XZ is the perpendicular bisector of AY. Find the length of AZ 4x + 4 3x + 7 Z AZ = Does point D lie on the perpendicular bisector of segment AB? Yes, because AD = BD = 4 No, because AD ≠ BD Not enough information to tell. Yes, because AD = BD = 5 Does point D lie on the perpendicular bisector of segment AB? Yes, because DA = DB = 5 Yes, because DA = DB = 4 No, because DA ≠ DB Not enough information to tell |
