identify the type of proof given.
statement reason
△abc is a right triangle, m∠c = 90° given
m∠a + m∠b + m∠c = 180° triangle sum theorem
m∠a + m∠b + 90° = 180° substitution property of equality
m∠a + m∠b = 90° subtraction property of equality
∠a and ∠b are complementary angles definition of complementary angles
two - column proof
geometric proof
paragraph proof
flow - chart proof

Explanation:

The proof is presented in a table with two columns - one for statements and one for reasons. This is the characteristic format of a two - column proof.

Answer:

Two - column proof
