I have to do this web quest table and i just want to make sure that i did this right. please help check this for me!
I did this in excel so i marked the questions with my answers with different symbols. it is a little confusing.
Probability of 2 randomly chosen angles being congruent chosen symbol=*
Probability of 2 randomly chosen sides being congruent chosen symbol=$
Probability of 2 consecutive angles being congruent chosen symbol=&
Probability of 2 consecutive sides being congruent chosen symbol= ^
Square
*1 $1 &1 ^1
Rectangle, but not a square
*1 $1/6 &1 ^0
Rhombus, but not a rectangle
*1/3 $1 &0 ^1
Quadrilateral, general
*0 $0 &0 ^0
Parallelogram, not a rectangle or rhombus
*1/3 $1/3 &0 ^0

Equilateral triangle

Right triangle, not isosceles
*0 $0 &0 ^0
Isosceles right triangle
*1/3 $1/3 &1/3 ^1/3
if you cant understand it im really sorry. ):

This seems partially right except for the fact that a parallelogram has 4 sides, so it should be 2/3, not 1/3
