How would I prove the congruency of these triangles?
2 answers:
Answer:
Step-by-step explanation:
In ΔADC & ΔABC,
Statement Reason
AD = BC Given
∠DAC ≅ ∠ACB {AB // BC , AC is transversal, ⇒ alternate interior angles are equal}
AC = CA Reflexive property
ΔADC ≅ ΔABC SAS congruent
AB = CD CPCT -> Corresponding Part of Congruent Triangles
Answer:
SAS
Step-by-step explanation:
<em>line </em>AB = <em>line</em> CD S = SIDE
AB = CD because the shape is a parallelogram and opposite sides of a parallelogram are equal.
Hence, proved AB = CD

Y - y₁ = m(x - x₁)
y - 3 = 4(22 - 2)
y - 3 = 4(20)
y - 3 = 80
