What statement must be true about <1 and <2 in order for lines m & n to be parallel? they are equal they are supplementary they are complementary m<1 is less than m<2 1 2 m n Line m intersects lines r,s,t, and w. Based on the given angles, which statement must be true? r & t are parallel r & w are parallel s & w are parallel figure NOT drawn to scale 85 100 80 w s t r Alternate interior angles are congruent. Consecutive interior angles are congruent. True or false. Find the value of x. 1 3 5 7 5x 3x +10 If two angles are complementary then they sum to If two angles are supplementary, then they sum to What is the measure of x? x 70' What is the measure of x? x 70' If cows don't moo, then dogs don't bark. If dogs don't moo, then cows don't bark. If cows bark, the dogs moo. If dogs moo, then cows bark. What is the converse of the statement? If cows bark, then dogs moo. If the grass is green, then the sky is not blue. If grass is not green, then the sky is not blue. If the grass is green, then the sky is blue. If the sky is not blue, then grass is green. What is the contrapositive of the statment? If the sky is blue, then grass is green. What is the conclusion of the statement? If an angle is 90 degrees, then it is a right angle. If an angle is 90 degrees then it is a right angle What is the hypothesis of the statement? If an angle is 90 degrees, then it is a right angle. If an angle is 90 degrees then it is a right angle All values are in degrees. Given: x = 78 y = ? 60 60 120 x y Cannot be determined 102 120 138 All values are in degrees. x 60 y The values of x and y are: x = 60 y = 60 x = 30 y = 90 x = 60 y = 90 Cannot be determined |
