Mathematics: Need ! triangle abc is shown below: prove all three angles of triangle abc add up to 180. the flowchart with missing reasons proves the measures of the interior angles of triangle abc total 180. which reason can be used to fill in the numbered blank spaces? alternate exterior angles theorem same side interior angles corresponding angles postulate

Need ! triangle abc is shown below: prove all three

it is 1/2

Step-by-step explanation:

The product of a lines slope M and the slope K of a perpendicular is -1:

M*K=-1

This implies

K=-1/M

since

M * -1/M=-1

In our example we are given a line of slope M=-2 therefore the slope K of a line to perpendicular to this line is:

M*K=-1

-2*K=-1

K=-1/-2=1/2
