In △ABC, CM is the median to AB and side BC is 12 cm long. There is a point P∈CM and a line AP intersecting BC at point Q. Find the lengths of segments CQ and BQ, if P is the midpoint of CM
To find the lengths of segments CQ and BQ, we can use the concept of similar triangles in △ABC.
Given that P is the midpoint of CM, we can conclude that CP and PM are equal in length.
Let's denote the length of CP (or PM) as x. Since P is the midpoint of CM, we can also conclude that AP and PB are equal in length. Therefore, AQ = QB.
Now, let's use the concept of similar triangles in △ABC. Since CM is the median, it divides side AB into two equal parts. Let's denote the length of CB (or BA) as c, and the length of BA (or CB) as b. Therefore, AB = 2c.
Using the concept of similar triangles, we have the following ratios:
(1) AQ / CQ = BP / PC
(2) CP / BP = CM / BA
Substituting the given values:
AQ / CQ = 1
CP / BP = x / c
CM / BA = 2x / (2c) = x / c
From equation (2), we can write CP / BP = x / c as:
x / c = (x + 12) / c
Cross-multiplying, we have:
cx = xc + 12c
cx - xc = 12c
c(x - x) = 12c
0 = 12c
c = 0
However, this implies that the length of CB (or BA) is 0, which is not possible. Therefore, there seems to be an error in the given information or question.
