Ethan created three triangles: triangle X, triangle Y, and triangle Z. If Triangle Y is congruent to triangle X and Triangle Y is congruent to triangle Z, which must also be true? The triangles are equilateral. The triangles are right triangles. Triangles X and Z are congruent. Triangles X, Y, and Z share one or more vertices.

The triangles are equilateral

Step-by-step explanation:

If Triangle Y is congruent to both angles pretty sure they would form up to 180degree because one angle would be 60degree due to it saying it is congruent to both of the x and z angles.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
