The figure shows a side panel of a skateboard ramp. kalim wants to confirm that the right triangles in the panel are congruent. what measurements should kalim take if he wants to confirm that the triangles are congruent by sas? explain.

Hmm... AB = BD ?

Step-by-step explanation:

Because we know that BC is perpendicular to AD, because it's 90 degrees. We just need to make sure that BC line is in the center.

I'm a little bit forgot about the Pre-Algebra lessons so you need to double check it.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
