The two column proof for the given angle addition has been carried out below.
<h3>How to Carry out two column proof?</h3>
1) m∠CZE = m∠1 + m∠2
Reason: Angle Addition Property
2) m∠FXH = m∠3 + m∠4
Reason: Angle Addition Property
3) m∠CZE = m∠FXH
Reason: Given
4) m∠1 + m∠2 = m∠3 + m∠4
Reason: Substitution Property
5) m∠1 = m∠3
Reason: Subtraction Property
6) m∠3 + m∠2 = m∠3 + m∠4
Reason: Substitution Property
7) m∠2 = m∠4
Reason: Subtraction Property

If the bases are the same then you can let the exponents be equal to each other. If the exponents are not the same then you will have to use logarithms to solve for x.
The solution lies in quadrant I
Answer:
180°
Step-by-step explanation: We are given the co-ordinates of ΔDEF as D(-1,6), E(1,3) and F(6,3).
Now, after rotation the co-ordinates of the new triangle D'E'F' are D'(1,-6), E'(-1,-3) and F'(-6,-3).
As we see that, the co-ordinates of triangle DEF are multiplied by negative sign to obtain the co-ordinates of triangle D'E'F'.
This means that, the triangle DEF is rotated 180° to form triangle D'E'F' because rotating 180 changes (x,y) to (-x,-y).
So, the rotation applied is 180° to ΔDEF.
