Question

Complete the paragraph proof of the following statement: The acute angels of a right triangle are complementary. 
Given: (Triangle) ABC with right angle C
Prove: (angle) A and (angle) B are complemetry. 
Proof: By the definition of a right angle, m<C=____?
By the triangle angle sum theorm, m<A + m<B + m<C =_____?
Subracting 90 from each side gives m<A + m<B=____?, so <A and <B are _____? by the definition of________?

directrix · Answer

By the definition of a right angle, m<C=____?
90
----------------------
By the triangle angle sum theorm, m<A + m<B + m<C =_____?
180
-----------------------
Subracting 90 from each side gives m<A + m<B=____?, so <A and <B are _____? by the definition of________? 

 90; complementary; complementary angles.
