15.) what is the converse of the congruent and parallel sides of a quadrilateral theorem.
a.) if a quadrilateral is not a parallelogram, then it does not have sides that are congruent
and parallel
b.) if a quadrilateral is a parallelogram, it has 4 congruent sides and 1 pair of parallel
sides.
c.) a quadrilateral is a parallelogram if and only if it has two sides that are congruent and
parallel
d.) if a quadrilateral is a parallelogram, then it has two sides that are congruent and
parallel

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
