In the figure below, lines l and k are parallel. Suppose that =m∠540° and =m∠432°. l k m n 1 3 2 4 5 Complete the statements below. By the angle addition property, = m∠2 m∠4m∠5°. We are given that =m∠432° and =m∠540°, so =m∠2°. We see that ∠4 and ∠3 are And since lines l and k are parallel, ∠4 and ∠3 are So, =m∠3°. We see that ∠1 and ∠5 are And since lines l and k are parallel, ∠1 and ∠5 are So, =m∠1°. Therefore, = m∠1 m∠2m∠3°. The relationship between ∠1, ∠2, and ∠3 is an example of the following rule. The sum of the interior angle measures of a triangle is°. Check Save For Later Submit Assignment Terms of Use
