Question

What is the length of the segment PD?
4 cm
6 cm
10 cm
12 cm

Answer 1

Indeterminate lol

Answer 2

you have similar triangles to play with

Answer 3

What is the length of the segment PD?

Answer 4

what have you deduced so far?

Answer 5

what property of similar triangles would help you determine an answer?

Answer 6

find DQ

Answer 7

side side side is a good response yes :)

namely ratio of side to side

Answer 8

6x = 4; when x = 4/6

18*4/6 = the part of the lower end of it

so 18 - 18*4/6 should give us the required answer

Answer 9

they are similar triangles.. all three angles are equal.. n by calculations length of PD is 6 cm

Answer 10

if i seened it right, i get 18-12

Answer 11

thank u

Answer 12

P=Q (corr. angle, PR//DE)
R=E (corr. angle, PR//DE)
Q=Q (common angle)
Therefore, QPR is similar to QDE
PR/DE = PQ/DQ
6/4 = 18/DQ
DQ= 12
PD=PQ-DQ=18-12 =6

Answer 13

It seems that I am a bit slow. Sorry for that.

Answer 14

its all those big fancy words you try to use, and hitting that enter key takes up valuable time as well ;)
