1.Which characteristics will prove that ΔDEF is a right, isosceles triangle?

segment DE is larger than segment EF, and their slopes are the same.
segment DE is larger than segment EF, and their slopes are opposite reciprocals.
The lengths of segment DE and segment EF are congruent, and their slopes are the same.
The lengths of segment DE and segment EF are congruent, and their slopes are opposite reciprocals

2.
How can you prove a triangle is an equilateral triangle?

Use the distance formula to see if at least two sides are congruent.
Use the slope formula to see if any sides are perpendicular.
Use the distance formula to see if all three sides are congruent.
Use the slope formula to see if any sides are parallel.
