Seth is using the figure shown below to prove pythagorean theorem using triangle similarity.
in the given triangle abc, angle a is 90° and segment ad is perpendicular to segment bc.
part a: identify a pair of similar triangles. (2 points)
part b: explain how you know the triangles from part a are similar. (4 points)
part c: if db = 9 and dc = 4, find the length of segment da. (4 points)

your correct answer is c. he organized a political resistance group based on islam.

im sorry for the poor quality answer.

c. he organized a political resistance group based on islam.

Part A: Triangle ABD is similar to Triangle ACD

Part B: Using HL Theorem, we can determine these 2 right triangles to be similar

Part C: DA = 3

Step-by-step explanation:

We can use HL (Hypotenuse-Leg) Theorem to help determine similarity. Since DA perpendicular bisects BC, we know that it forms the altitude and forms right triangles, which gives us legs and a hypotenuse,

To find DA, we are given right triangle ACD. We know that one leg, CD, is equal to 4. We also know that 3-4-5 is a Pythagorean Triple, so DA would be 3 and AC would be 5.

The area left is equal to about 2686 (if we will round to the nearest whole number).

Step-by-step explanation:

The area of the backyard that will be left will equal to the area of his backyard minus the area of the circular pool. So we can write it as...

The area left = (area of the backyard) - (area of the pool)

The area left =

The area left =

The area left ≅ 2686
