Q6)I agree with Jack because this is an equilateral triangle so all the angles are equal so they each would be 60 degrees.

Q7)a and b are false. c and d are true.

Q8)no because 43 plus 74 is 117 and 180 minus 117 is 63 and an isosceles has two same angles this one doesn't.

Q9)100 and 51 111 and 40

Q10)60 degrees
