Acity grid of anytown, u. s.a is shown on the grid below. the fire department is represented by quadrilateral rstu. another fire department is opening in a different part of the city to maximize fire protection. the size of the new department’s property must be congruent to the older department. vertices a and b are plotted on the grid to represent two vertices of the new fire department quadrilateral abcd.. . what could be the ordered pairs representing vertices c and d of quadrilateral abcd so that the new fire department is congruent to the old fire department?
answer: 6.561 or 6.6
10 * 0.90^4 = 6.561
d. 12, 6, 7
for the triangle to have non-zero area, the sum of the shortest two sides must exceed the longest side.
a: 3 + 7 = 10 . . triangle has zero area
b: 4 + 5 < 10 . . sides don't meet
c: 6 + 8 = 14 . . triangle has zero area
d: 6 + 7 > 12 . . these form a triangle with non-zero area.
