M(8, 7) is the midpoint of rs. the coordinates of s are (9, 5). what are the coordinates of r?
a)(10, 3)
b)(8.5, 6)
c)(16, 14)
d)(7, 9)

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.

The vertices of a triangle are a(7.5), b(4,2), and c19. 2). what is

What type of symmetry does a rhombus have?
