17. A group of students on a hiking trip wants to find the distance
AB across a pond (see the following figure). One student
suggests choosing any point C, connecting it with B,
and then finding point D such that ?DCB > ?ACB and
. How and why does this help in finding the distance
AB?





26. Draw two quadrilaterals such that two angles and an included
side in one quadrilateral are congruent, respectively,
to two angles and an included side in the other quadrilateral.
However, the quadrilaterals are not congruent.



10. Given A, B, and C as vertices, use a compass and a

15. Answer each of the following:
a. Draw a line and any two points A and B so that is
parallel to the line. Find the image of under a translation
from A to B.
b. Draw a line and any two points A and B so that is
not parallel to . Construct , the image of under the
translation from A to B.
c. How are and in part (b) related? Why?



4. We have seen that equilateral triangles, squares, and regular
hexagons are the only regular polygons that will tessellate
the plane by themselves. However, there are many
ways to tessellate the plane by using combinations of
these and other regular polygons, as shown in the following
figure:


It should be just six of them Price $45.00 Because it accepted $9.00 I will have to put the ramining on the bonus correct. I cannot drwan the diagram so can you post then Please Scott.
