SOLUTION: given rectangle ABCD and AE is congruent to de, prove angle EDC is congruent to angle EAB

Algebra ->  Geometry-proofs -> SOLUTION: given rectangle ABCD and AE is congruent to de, prove angle EDC is congruent to angle EAB       Log On

AE ≅ DE
ΔAED is isosceles
m∠EDA = m∠EAD
m∠ADC = m∠DAE = 90o
m∠EDA + m∠ADC = m∠EAD + m∠DAE
m∠EDC = m∠EAB
∠EDC ≅ ∠EAB
