Which pairs of polygons are similar?

The trapezoids and the rectangles are similar

Step-by-step explanation:

we know that

If two figures are similar

then

The ratio of their corresponding sides is equal

We will proceed to verify each case

case A) Right triangles

------> is not true

therefore

the right triangles are not similar

case B) Isosceles triangle and equilateral triangle

Are not similar, because the first  is an isosceles triangle and the second is an equilateral triangle

case C) Trapezoids  

------> is true

therefore

the trapezoid figures are similar

case D) Rectangles

------> is true

therefore

the rectangles are similar

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

the answer is 24
