Explanation:

Question 3.

Jenny says, “Polygon N, Polygon R, and Polygon S are all regular quadrilaterals!” Is she correct? Why or why not?

Answer:

No, Jenny is not correct because polygon N, polygon R nor polygon S are not having four equal sides nor 4 equal angles to be said as regular quadrilaterals.

Explanation:

Question 4.

“I have six equal sides and six equal angles. I have three sets of parallel lines. I have no right angles.”

a. Write the letter and the name of the polygon described above.

b. Estimate to draw the same type of polygon as in part (a), but with no equal sides.

Answer:

a) ‘I have six equal sides and six equal angles. I have three sets of parallel lines. I have no right angles.”

Polygon U is said to be a regular hexagon.

Explanation:

b)

Explanation:

In part a, the figure is having six sides of equal length of sides.

The figure drawn, is having six sides of different lengths of sides.

Question 1.

Match the polygons with their appropriate clouds. A polygon can match to more than 1 cloud.

Answer:

Explanation:

Every figure has its own attributes, which are different.

Every polygon is matched according to its attributes.

Question 2.

The two polygons below are regular polygons. How are these polygons the same? How are they different?

Answer:

They are same because each polygon drawn is made up of same sides.

They are different because they have different angles.

Explanation:

Given figures are Hexagon and Triangle.

Question 4.

Lucia drew the polygons below. Are any of the polygons she drew regular polygons? Explain how you know.

Answer:

Figure Pentagon which Lucia drawn is regular polygon because a regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).

Explanation:

Figures given are different in terms of sides and angles.

First and Second figures drawn are having different lengths of sides.

Third figure drawn is having same sides of equal lengths. It is said as regular polygon.
