Compare corresponding angles to decide if they are congruent. Since AB is horizontal and BC is vertical, ∠B is
(select)
. Similarly, ∠E is
(select)
.
m∠B = m∠E =
°
By the Triangle Sum Theorem, m∠C is equal to
°.
By the Triangle Sum Theorem, m∠D is equal to
°.
So, ∠A
(select)
∠D, ∠B
(select)
∠E, and ∠C
(select)
∠F. The triangles have
(select)
of congruent corresponding angles.
AB is horizontal and its length is
units. BC is vertical and its length is
units.
By the Distance Formula, AC is .
DE is horizontal and its length is
units. EF is vertical and its length is
units.
By the Distance Formula, DF is .
So, AB ≅
(select)
, BC ≅
(select)
, and AC ≅
(select)
.
△ABC
(select)
△DEF by
(select)
.
