Answer:
Supplementary angles are two angles that add up to 180° degrees. • Complementary angles are two angles that add up to 90° degrees. • Adjacent angles share a vertex and a common side. • Congruent angles have the same measure. • An obtuse angle triangle has one angle that is greater than 90 degrees. • A triangle with angles 45°, 45°, and 90° would be a Isosceles triangle
