Answer: b) ΔADC ≡ ΔBCD by SAS
<u>Step-by-step explanation:</u>
Step 1: AD = BC SIDES are congruent
Step 2: ∠ADC ≡ ∠BCD ANGLES are congruent
Step 3: DC = DC SIDES are congruent
The proof is using Side-Angle-Side (SAS)
Look at the angles in step 2. These are the triangles you are proving congruency for: ΔADC ≡ ΔBCD
Answer:

Step-by-step explanation:
<u>Step 1: Convert into an equation</u>
Nine less than one forth of a number is 6

<u>Step 2: Add 9 to both sides</u>



<u>Step 3: Multiply both sides by 4</u>
