A,because I subtract 3 minus 1 equal 2.
Answer:
rationalizing
Step-by-step explanation:
The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
Answer:
These are the properties of a parallelogram
• Opposite angles are equal
• The sum of all the angles is equal to 360 degrees
• Opposite angles are equal
• When the diagonals of a parallelogram are drawn, they bisect each other
• When a diagonal is drawn to separate the parallelogram into two, the two separate sides are equal when compared
• The sum of two adjacent angles in parallelogram is equal to 180 degrees
Step-by-step explanation:
For example,
Opposite angles (A and D) and (B and C) are equal
The sum of all the angles give 360 degrees, angles A + B + C + D = 360
Side AB is equal to side CD (/AB/ = /CD/)
The sum of adjacent angles A and C gives 180 [angles (A + C ) = 180]
Choose the option similar to any of these properties in the question
The largest area would be a square with sides 360/4, or 90 yds. each. The area would be 90x90, or 8100 yds². ☺☺☺☺
