Anyone teach me the angles in theorms

The alternate segment theorem says that angles BAC and BCE are congruent, so

###

Triangle ABC is isosceles, which makes angles ACB and ABC congruent, and the sum of the interior angles of any triangle is 180 degrees, so

###

The alternate segment theorem also says that angles DCF and CAD are congruent. Angles DCF, ACD, ACB, and BCE are supplementary, so

Then

###

The inscribed angle theorem says that angle COB has twice the measure of angle BAC, so

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
