Polar bears hunt other animals because they are predators. They can be very
aggressive, or mean. Polar bears have large teeth so they use them to bite into their prey
easily. Polar bears have long, sharp, claws. They use their claws to scratch their prey. Their
claws are also used to climb or grip the ice. Polar bears eat fish, seals, walruses, birds, and
small sea llons. Polar bears eat other animals because they are carnivores or meat eaters.
Their white fur allows them to camouflage so they are able to blend in to their environment.
This helps the polar bear to sneak up on their prey. Polar bears are patient because they wait
many hours for their prey to surface to the water before they catch it.

Answer:
DEF are respectively the midpoints of sides AB, BC and CA of triangle ABC, then: Ratio of area of triangle DEF : area of triangle ABC = 1 : 4
Solution:
In the given question, we know Triangle DEF formed with midpoints is similar to the Outer Triangle ABC
On the basis of the similarity, we can say,
If two triangles are similar then the ratio of their area is equal to the square of the ratio of their corresponding sides
Mathematically can be written as :-
\frac{\text {area of triangle } D E F}{\text {area of triangle ABC}}=\left(\frac{D E}{A C}\right)^{2}
area of triangle ABC
area of triangle DEF
=(

DE
)

Since, DECF is a parallelogram. So DE = FC
On substituting:
\frac{\text {area of triangle } D E F}{\text {area of triangle ABC}}=\left(\frac{F C}{A C}\right)^{2}
area of triangle ABC
area of triangle DEF
=(
AC
FC
)

Also, F is the midpoint of AC
\text { So } \mathrm{AC}=2 \times \mathrm{FC} So AC=2×FC
\begin{gathered}\begin{array}{l}{\frac{\text {area of triangle } D E F}{\text {area of triangle } A B C}=\left(\frac{F C}{2 F C}\right)^{2}} \\\\ {\frac{\text {area of triangle } D E F}{\text {area of triangle } A B C}=\frac{1}{4}}\end{array}\end{gathered}
area of triangle ABC
area of triangle DEF

Hence ratio of area of triangle DEF and triangle
ABC is given as:
Ratio of area of triangle DEF : area of triangle ABC = 1 : 4
