Question

Step 2 - Identify which formula we use to prove certain properties of polygons.
Below are properties of triangles/quadrilaterals you’ve been working with closely. Look at the properties given, then match it with the formula you would use to prove it. (Hint: think about the type of answers we expect from each of the formulas listed - use your answers from Step 1 to help!)
**You could use each choice more than once!


_____ 1.) Both pairs of opposite sides are congruent.
_____ 2.) Both pairs of opposite sides are parallel
_____ 3.) Diagonals are congruent.
_____ 5.) Diagonals are perpendicular.
_____ 6.) Sides of polygon create a right angle
_____ 7.) A triangle is isosceles/equilateral.

a.) Midpoint Formula
b.) Slope Formula
c.) Distance Formula

I just need a little help. I'm not asking for the answer, but my teachers aren't responding at the moment. So could somebody give me a few pointers on how to start this? Thank you so SO much. You're a huge help

Answer 1

1c since sides are congruent only if their lengths are equal
2b since parallel lines have the same slope
