Suppose △abc≅△def, m∠a=87°△abc≅△def, m∠a=87°, and m∠e=56°m∠e=56°.
what is m∠cm∠c?
56º
87º
37º
93º

If the trianles are congruent, the sum of three either angles would be equal to 180

so, 87+56+c = 180

c = 180-143

c = 37

SO OPTION C IS YOUR ANSWER

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
