Determine whether side-angle-angle (SAA) is a valid means for establishing triangle congruence. In this case, you know
the measure of a side, an adjacent angle, and the angle opposite to the side. If it is a valid criterion, explain why. If it is
not valid, use GeoGebra to create a counterexample demonstrating that it doesn't work and give an explanation. If you
construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

40 x 50 = 2000

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
