Points a, b, and c form a triangle. complete the statements to prove that the sum of the interior angles of δabc is 180°.

because a triangle is half of a square even iif it is not a right triangle than the angles have to add up to 180 degrees. because a square is 360 degrees. if the angles are more or less than 180 degrees combines the points witll not touch eachother therfore it will just be a line and not a shape of a triangle.

(not sure if this is what you were looking for but i hope it and if not that i am sorry.)

∠3 ≅ ∠5 and ∠1 ≅ ∠4: alternative angles theorem

m∠1 = m∠4 and m∠3 = m∠5: congruent angles have equal measures.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
