Is there a picture to go with this? @Mrfootballman97

Do you know if it is one of the base angles? Or is it the angle at the top of the triangle?

Trapezoids sum.. I believe is 360
MathLegend
  • MathLegend
Interior angles sum is 360... right?

  • anonymous
ahhhhhh ok then. So could the angles be anything as long as they add up to be 360?
MathLegend
  • MathLegend
They can't be any number... we would have to know what Isosceles is.

Opposite angles are Supplementary

one guy said this: Since it is an isosceles trapezoid, the base angles are the same. By property of // lines, you can find c and b. ^ (sum of interior angle of // lines = 180 degrees)

Callisto was the person

He is correct

  • anonymous
Yup
MathLegend
  • MathLegend
Being that opposite angles are supplementary... we know that Supplementary is 180, right?
MathLegend
  • MathLegend
180 - 57 = 123

so 123 is the top angles measure?

Oh i see THANKS!
MathLegend
  • MathLegend
Yes, and if you notice they sum to 360 :)
