Answer:

  A.  The reflection preserves the side lengths and angles of triangle . The dilation preserves angles but not side lengths.

Step-by-step explanation:

Reflection is a rigid transformation. It preserves both angles and side lengths. Dilation preserves angles, but changes all lengths by the same scale factor.

<h3>Application</h3>

The described triangle was subject to reflection, which preserves angles and lengths. It was also subject to dilation, which preserves angles, but not lengths.

The appropriate description is that of choice A.

The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °, what is the measurement of the fourth
Diano4ka-milaya [45]
<h2><u>Question</u>:-</h2>

The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °, what is the measurement of the fourth angle?

<h2><u>Answer</u>:-</h2>

<h3>Given:-</h3>

The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °

<h3>To Find:-</h3>

The measurement of the fourth angle.

<h2>Solution:-</h2>

By angle sum property of a quadrilateral,

Sum of all the interior angles = 360 °

So, let the fourth angle be x

\therefore 85 ° + 54 ° + 96 ° + x = 360 °

\therefore 235 ° + x = 360 °

\therefore x = 360 ° - 235 ° = 125 °

<h3>The measurement of the fourth angle is <u>1</u><u>2</u><u>5</u><u> </u><u>°</u>. [Answer]</h3>
