Hope this helped have an amazing day!

Answer 2

C. Right and isosceles

Step-by-step explanation:

Since two sides of the triangle are equal in length (
`DE` and
`DF`), this means that the triangle is an isosceles triangle. Since
`EF` is the hypotenuse of this triangle, it also means that the triangle is a right-angle triangle (the hypotenuse refers to the longest side of a right triangle). Therefore, we can conclude that ΔDEF is right and isosceles.

Hope this helps :)
