Select the correct answer from each drop-down menu. D
Points A, B, and form a triangle. Complete the statements to prove that the sum of the Interior angles of AABC Is 180º.
Statement
Reason
Points A, B, and form a triangle.
given
Let DE be a line passing through Band parallel to AC. definition of parallel lines
23 - 25 and 21 - 24
m21 = m 24 and m23 = m25
m24+ m2 2 + 25 = 180°
m21 + m22+ m23 = 180°
angle addition and definition of a straight line
substitution
renred

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
