Me pueden ayudar a poner un triangulo dentro de un texto con relleno y borde, que siga editable para modificarlo y crear otros numeros, debe verse un color en la parte de arriba, y la parte de abajo debe ser un angulo del triangulo en otro color
You draw a rectangle and a triangle stacked on top of each other.
Then you type the number on top of that.
Then you select all of that and Object > Clipping mask > Make (or cmd+7 / Ctrl+7)
If you then select the number with the direct selection tool, you can apply a stroke to it. But that stroke will not look good, because it eats away from the fill. And there is no hack to prevent that. So for that outline it would be best to have a second number below the other one.
