Question

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.

The figure shows triangle ABC with right angle at A and segment AD. Point D is on side 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. Show your work. (4 points)

Answer 1

do you know the Pythagorean Theorem ?

Answer 2

dont really understand it i get most of the question im stuck on part c

Answer 3

ok do you can post the attached image with this right triangle ?

Answer 4

the link is on it i dont know how to post the image

Answer 5

ok i will try draw it

Answer 6

yes

Answer 7

thats the one

Answer 8

ok so for part C to solve it just you need to know the amplitude theorem in a right triangle from the right angle on hypotenuse

Answer 9

could you explain that?

Answer 10

because nothing in my online lessons went over amplitude therom

Answer 11
