First Semester Final Review

Determine if each set of 3 lengths will make a triangle or not. A triangle is possible if the length of any two sides has a sum greater than the third side. Will Make a Triangle 5, 5, 5 4, 7, 9 3, 6, 5 Will not make a Triangle 1, 1, 2 8, 2, 5 6, 6, 13 Match each word to its definition Centroid Point of concurrency of the medians Incenter Point of concurrency of the angle bisectors Circumcenter Point of concurrency of the perpendicular bisectors Orthocenter Point of concurrency of the altitudes Find the distance from (2, 6) and (-1, 10).Use the distance formula. 5 Find the m∠CBD 109˚ Match the statement to its variation.If I study, then I will pass. converse If I pass, then I studied inverse If I don't study, then I won't pass contrapositive If I don't pass, then I didn't study. Match the pairs of angles with their names Angles 5 and 6 Linear Pair Angles 3 and 8 Alternate Interior Angles Angles 4 and 7 Corresponding Angles Angles 2 and 7 Alternate Exterior Angles Angles 5 and 7 Vertical Angles Find the value of x. x = 8 A is between J and K. AJ = 12 and JK = 15. Find AK. AK = 3 Match each property to a statement that illustrates it. Reflexive Property JK = JK Symmetric Property If AB = CD, then CD = AB. Transitive Property If AB = CD and CD = EF, then AB = EF. Multiplication Property If m∠A = 40˚, then 2m∠A = 80˚ Addition Property If m∠A = 40˚, then m∠A + 20 = 60˚ Substitution Property If x + y = 90 and x = 30, then 30 + y = 90. Find the supplement of a 45˚ angle. 135˚ Find the complement of a 72˚ angle. 18˚ Are the lines with these equations parallel, perpendicular or neither?y = 3x + 6y = -3x +6 parallel perpendicular neither
