Addition Property of Equality

Answer:

Addition Property of Equality

Step-by-step explanation:

Given:3 ● m∠Q − 17 = 30, then 3 ● m∠Q = 47.

3 ●m∠Q - 17 = 30

Here we have to find the m∠Q. To find the angle use inverse operation of subtraction.

The inverse operation of subtraction is addition.

Here we have to get rid of -17, the inverse operation of "-" is "+"

So, add +17 on both sides, we get

3 ●m∠Q - 17 + 17 = 30 + 17

3 ●m∠Q = 47

Therefore, we used Addition property of equality.

The transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.

<h3>What is transformation?</h3>

A transformation is a general term for four specific ways to manipulate the shape or position of a point, a line, or a geometric figure.

We have,

Coordinates of a pentagon Q.

(2, 4), (3, 7), (7, 5), (5,4), and (4,2).

Coordinates of pentagon Q'.

(-2, -4), (-3, -7), (-7, -5), (-5,-4), and (-4,-2).

We see that the coordinates of each point of the pentagon Q have changed their position as negative coordinates in pentagon Q'

The coordinates of pentagon Q are in (x, y) which can be assumed to be in the first quadrant of the coordinate plane.

The coordinates of pentagon Q' are in (-x, -y) which is in the 3rd quadrant.

From the first quadrant to 3rd quadrant there is a rotation of 180°.

Thus the transformation of pentagon Q to pentagon Q' is a clockwise rotation of 180° about the origin.
