1. Angle: <span>the union of two rays that have a common endpoint.
</span>2. Acute Angle: <span>an angle whose measure is greater than zero and less than 90°
</span>3. Right Angle: <span>an angle whose measure equals 90°.
</span>4. Obtuse Angle: <span>an angle with a measure greater than 90° but less than 180°.
</span>5. Bisector of an Angle: <span>a set of points which divides the angle into two angles of equal measure.
</span>6. Perpendicular Line: lines that intersect to form right angles.
Answer
Therefore the answer is 82.
The area is A=1/2aP
a=apathem
p=perimeter
