If segment AB is congruent to segment CD and segment AB is parallel to segment CD, which of the following steps is not correct in proving that ABCD is a parallelogram? a If two parallel lines are cut by a transversal, the alternate interior angles are congruent. b SAS: If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. c Definition of perpendicular lines d CPCTC: Corresponding parts of congruent triangles are congruent.

C

Step-by-step explanation:

Perpendicular lines are irrelevant. A is to create a triangle and to show 2 angles in the triangles are congruent. B is to prove the 2 triangles are congruen. D is to prove that AC and BD are congruen. no where is perpendicular lines involved.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
