Choose the abbreviation of the postulate or theorem that supports the conclusion that the triangles are congruent. given: ∠c, ∠f are rt. ∠'s; ∠b = ∠e; bc = ef

Angle Side Angle

Step-by-step explanation:

Here, the following triangles are congruent by using Angle Side Angle

∠c=∠F(90°)     (Angle)

BC=EF (Given)  (Side)

∠B=∠E (Given)  (Angle)

By using Angle Side Angle criteria, we can say that

Both the triangles are congruent

Hence, Both triangles are congruent by using ASA criteria.

d. is the correct answer

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
