Given: ABCD is a parallelogram.
Prove: ZA 2C and ZBZD
By the definition of a , AD // BC and AB / DC.
Using, AD as a transversal, ZA and 2 are same-
side interior angles, so they are
Using side as a transversal, ZB and ZC are
same-side interior angles, so they are supplementary.
Using AB as a transversal, ZA and ZB are same-side
interior angles, so they are supplementary.
Therefore, ZA is congruent to 2C because they are
supplements of the same angle. Similarly, ZB is
congruent to

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

nswer: a   y-axis

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
