1. Which of the following statement is true?
a. Triangles and quadrilaterals are both polygons.
b. Triangles and quadrilaterals are both a closed plane figure
c. All A and B is true
2. Which of the following statements present the relation of triangles and quadrilaterals?
a. if you divide a quadrilateral diagonally, you will have two triangles.
b. if you divide a quadrilateral diagonally, you will have three triangles.
c. If you divide a quadrilateral diagonally, you will have four triangles.

Step 1

1. A triangle is a polynomial with three sides. And a quadrilateral is a polynomial with four sides.

Hence, triangle and quadrilaterals are both polynomials.

A polynomial is a closed plane figure.

Hence, triangles and quadrilaterals are both a closed plane figure.

Therefore, all A and B are true.

Step 2

2. If we divide a quadrilateral diagonally we get two closed plane figures with three sides. A closed plane figure with 3 sides is called a triangle.

Hence, if we divide a quadrilateral diagonally then we will have two triangles. * For every student we do a unique answer
