20. Write a two-column proof:
Given: BAC = DAC, DCA = BCA
Prove: BC = CD

Given:

To prove:

Solution:

The two-column proof is:

Statement                                        Reason

1.                            1. Given

2.                           2. Given

3.                                      3. Common side

4.                          4. ASA congruent postulate

5.                                     5. CPCTC

Hence proved.

step-by-step explanation:

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
