Sure, have you looked on YouTube? I make my son watch math how to videos, when he has a hard time understanding.
You might have to look through a few different people channels before you find one person that you like, some are easier to follow than others. I also have watched the videos so I can help my kids with their homework? |

two circles of equal size intersecting.
circle a and circle b are congruent. CD is a chord of both circles. If a radius is 10 feet and CD= 16 feet, how long is AB?

you can also set up a right triangle so that the radius is the hypotenuse, short side is 1/2CD, and long side is radius - 1/2 ab
cd and radius are known, so it becomes an algebra equation |

Are any formulas given? Or is this a problem where the student has to figure out the formula?
AB is 8 ft. |

Hint: There is a 3,4,5 triangle in there. It is a problem designed to recognize it.

C to the center of the circle is the radius 10. C0 =8. Use pathagorium therom to figure total horizontal leg then subtract radius from length. Then times length by 2. That will give you the length AB.
