17. The measure of the height AD of a ABC with respect to the base BC
is 4 cm. P is a point on BC such that BP = 3 cm. and arABP = arAPC.
Find the measure of PC.
Answers
Answer:
The measure of PC is 3 cm
Step-by-step explanation:
given : AD = 4 cm
we have to find the measure of PC
given that the area of triangle ABP= area of triangle APC.
therefore ,
area of triangle ABP
\begin{gathered}= \frac{1}{2}\times base \times height \\\\= \frac{1}{2}\times BP \times AD\end{gathered}
=
2
1
×base×height
=
2
1
×BP×AD
similarly area of triangle APC
\begin{gathered}= \frac{1}{2}\times base \times height \\\\= \frac{1}{2}\times PC \times AD\end{gathered}
=
2
1
×base×height
=
2
1
×PC×AD
Since , area of triangle ABP= area of triangle APC
\frac{1}{2}\times BP \times AD = \frac{1}{2}\times PC \times AD
2
1
×BP×AD=
2
1
×PC×AD
BP = PC
thus the value of PC = 3 cm
