You are watching: Which statements are true about polygons? check all that apply.

### Answers

True declaration are:

The political parties of a polygon are segments that intersect exactly two other segments, one at every endpoint

If every one of the sides of a convex polygon are extended, none will contain any kind of points that room inside the polygon

The extension of at the very least one next or diagonal in a concave polygon will contain a allude that is inside the polygon

Step-by-step explanation:

* Lets explain what is the polygon

- The polygon is any type of figure contends least 3 sides

- Every polygon is either convex or concave

- A convex polygon is a polygon v all its interior angles much less

than 180°

- every the diagonals of a convex polygon space inside the polygon

- regular Polygons are constantly convex

- all concave polygons room irregular

- The polygon is concave if at least one that its inner angles is greater

보다 180°

- In a concave polygon, at the very least one diagonal line passes external the figure.

- A concave polygon must have at least four sides

* now lets discover the true statements about the polygon

- every sides and all angle in a polygon space congruent ⇒ no true

(Regulars polygons only have equal sides and also equal angles)

- The sides of a polygon room segments the intersect precisely two other

segments, one at each endpoint ⇒ True

- In a polygon, all segments v a usual endpoint room

collinear ⇒ not true

(collinear way the angle between them is 180°)

- If all of the sides of a convex polygon are extended, nobody of them

will contain any points that are inside the polygon ⇒ True

- The expansion of at least one next or diagonal in a concave polygon

will contain a suggest that is inside the polygon ⇒ True

B D and E

Step-by-step explanation:

1) b) 5

3) a) D

4) b) B"

5.) a)

6.) 88°

9) 2,160°

10.) d) The number of sides is even

15.) a) Reflecting about the y-axis and also then rotating 90° counterclockwise

16) b) (0, 0)

17.) c) This statement is true

18.) a) This declare is false. If a succession of rigid activities maps a pre-image to an image, the pre-image and the image are congruent no matter the details of the sequence of rigid motions

Step-by-step explanation:

1) b) 5 A translate into is a type of rigid revolution that preserves the shape and also dimensions of the pre-image in the image

3) a) D. The letter D has an horizontal heat of symmetry

4) b) B". The reflection of one object around a heat is as much behind the mirror as the object is in prior

5.) a) The arrow will allude in the southwest direction

6.) 88°. A 272° rotation clockwise, is tantamount to a 360° - 272° rotation. Anticlockwise

9) 2,160°.

One rotation = 360°, 6 rotations = 6 × 360° = 2,160°

10.) d) The number of sides is even

The presence of a line symmetry provides equal variety of sides ~ above both face of the line of symmetry, which gives an also an even number of sides

15.) a) Reflecting around the y-axis and also then rotating 90° counterclockwise

Reflecting throughout the heat y = -x, provides (x, y) → (-y, -x)

Reflecting around the y axis gives, (x, y) → (x, -y))

Rotation 90° counterclockwise provides (x, -y) → (-y, -x)

16) b) (0, 0),

Reflection about the line y = x offers (x, y) → (y, x)

Reflection about the heat y = -x provides (x, y) → (-y, -x)

When, (x, y) = (0, 0), (y, x) ≡ (-y, -x)

when

17.) c) This statement is true,

A rigid motion entails the equal readjust of all collaborates on the pre-image to type the image

18.) a) This declare is false. If a sequence of rigid movements maps a pre-image to an image, the pre-image and also the photo are congruent no issue the details of the succession of strictly motions

The preimage and the image formed by a rigid transformation are always congruent
