Daniel is constructing a fence that consists of parallel sides line AB and line EF. Complete the proof to explain how he can show that m∠GKB = 120° by filling in the missing justifications. A. 1. Alternate Interior Angles Theorem; 2. Definition of Congruence B. 1. Alternate Exterior Angles Theorem; 2. Substitution Property C. 1. Definition of Congruence; 2. Alternate Interior Angles Theorem D. 1. Substitution Property; 2. Alternate Exterior Angles Theorem

Every angle is either 60° or 120° and you find m<L using the supplementary angles theorem. But you can also use Alternate Exterior Angles, Alternate Interior Angles

Step-by-step explanation:

Angle L is 60° so every angle is either 120° or 60°. The reason for this is because of the supplementary angles theorem where the sum of the two angles are 180°.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
