A baseball field has four bases that form the shape of a quadrilateral. If someone invented a new game similar to baseball that had four extra bases in the field, what type of polygon would the bases form?

A. pentagon
B. octagon
C. hexagon
D. decagon

The bases of the field and the four extra bases would form an octagon. Therefore, the answer is B. octagon.

Which is the most descriptive name for the shape below?

shape
A. square
B. rhombus
C. quadrilateral
D. rectangle

The most descriptive name for the shape below would be a rhombus because it has four equal sides, opposite equal angles, but its angles are not 90 degrees making it different from a square or a rectangle. Therefore, the answer is B. rhombus.

Which figures appear to be congruent?

An image of 5 triangles on a 14 by 12 grid is shown.Triangle 1 has a base that is 4 units long. The upper vertex is 4 units above the midpoint of the base. To the right, triangle 2 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned in the triangle at the lower left vertex. Below triangle 1, triangle 3 has a horizontal leg that is 3.5 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 4 is toward the center of the grid. It has a horizontal leg that is 1 unit long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the upper right vertex. Triangle 5 is to the lower right. It has a horizontal leg that is 6 units long and a vertical leg that is 4 units long. A small square is positioned inside this triangle at the lower left vertex.
A. 1, 2, and 3

Based on the given information, triangles 1 and 3, and triangles 2 and 3 appear to be congruent because they have the same dimensions. Therefore, the answer is D. 2 and 3.

Which statement is true about the following pair of rectangles?

Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.

To determine if the two rectangles are similar, we need to compare the ratios of their corresponding side lengths. The ratio of the length to the width of the larger rectangle is 60:30 or 2:1, and the ratio of length to the width of the smaller rectangle is 3:6 or 1:2. These ratios are equivalent because 2:1 is the same as 1:2. Therefore, the two rectangles are similar, and the answer is D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.
