the figure below shows line t, which intersects segment ab:

segment ab is intersected by line t. point c is on line t.

in the image above, line t is a perpendicular bisector and angle 4 is congruent to angle 6. write a paragraph to prove that point c is equidistant from points a and b.

"if it is my birthday, then it is snowing"

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
