Answers
Answer:
1. Polygon
2. Convex
3. 5
4. n-gon
5. (no options)
6. Polygon ABCDE
For more answers, there is neither figures nor options... So how can we answer?
Step-by-step explanation:
Hope it helps you :)
Answer:
1.Polygon
2.Concave
3. 5
4. maybe n-gon
because
(A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.)
(In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka "eleven" and –gon "corner", is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim "eleven".)
I don't know any meaning of gon so,
it maybe n-gon
5. (only one option provided)
6. Polygon ABCDE would be correct in this 4 options
7.(only one option provided)
8.∠ABO
9.(you didn't gave the polygon ) so, it could be all
10. (A), (B), (D)
Step-by-step explanation:
6. (you can name it anyway even Alpabatical order or randomly)
9. Consecutive sides are two sides that have an endpoint in common. The four‐sided polygon in Figure could have been named ABCD, BCDA, or ADCB, for example. It does not matter with which letter you begin as long as the vertices are named consecutively. Sides AB and BC are examples of consecutive sides.
10.Polygons. A polygon is any closed, 2-dimensional figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.
