Which statements about the diagram are true? Select three options. D E + E F greater-than D F
Triangle D E F is an isosceles triangle.
5 less-than D F less-than 13
D E + D F less-than E F
Triangle D E F is a scalene triangle.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
