Yan knows that 21 and 25 are corresponding angles. She also knows
that supplementary angles have
measures that add to 180°. How could
Yan use these two facts to deduce that
Llis supplementary to 26?

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

to complete this square you have to rotate about the origin 270 degrees clockwise.
