Given an exterior angle of a triangle is greater than either of the remote interior angles, then prove the sum of the degree measures of a triangle is less than or equal to 180 degrees. (Notice you are not beginning with or using the parallel postulate to prove this!) Don not use parallel postulate to prove!
2.6 The vertices of a triangle are (2,-7,3), (-1,5,8), and (4,6,-1). Is the triangle acute, right, or obtuse? Explain your reasoning using the Law of Cosines to find the measurement of the angles.
please do not use “compact” term, i have not covered that in
class

Prove: If n=2^(k)−1 for k∈N, then every entry in row n of pascal's triangle is odd.
23.4 Let ABC be any triangle, let DE be a line parallel to the base, and let F be any point on DE. Show that the area of the union of the two triangles DBF and ECF is less than or equal to one-fourth the area of the whole triangle, with equality if and only if D and E are the midpoints of AB and AC.
