Complete the table to show corresponding parts in the three figure

Corresponding parts:

Angles, sides, or vertices of two or more figures that are located in the same position when the figures are aligned.

The term corresponding means that the parts of two or more figures match when turning, flipping or sliding them. In Figure 1, If we turn the object in green  a certain angle, we will get to match both the sided and the angles of these two objects. Therefore, object in red and object in green are corresponding.

Step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
