Answer 1

Answer:

don't know what

please brainiest my answer

Answer 2

Answer:

1)ans:-option c):- 3 daigonals

2)ans:-option d):-nonagon

3)ans:-option b):-100°

4)ans:-option c):- 360°

5)ans:-option b):-right angle

6)ans:-option c):-7

Step-by-step explanation:

1):-a hexagon has 6 corner and and if we draw daigonals by join 2 corners of each diagonal then total 3 daigonals are formed.

2):-A nonagon has 9 sides.

3):- the 4th angle is 100° because the sum of 4 angles of a quadrilateral is 360° so according to the question if we do the sum of the 3 angle the we substract the with 360 then the answer is 100

4):-A parallalogram is also a quadrilateral so the sum of 4 angle are 360°

5):-you can draw a square and then draw 2 straight lines to join the corners of a square then you can see the result all the angle of the daigonal come 90 or right angle

6):- A heptagon has 7 sides.
