How are the triangles the same? - Answers

-- both triangles lie flat -- both triangles have three sides -- both triangles have three vertices (vertexes, points) -- both triangles have three inside angles and three outside angles -- neither triangle has more than one obtuse angle or more than one right angle inside it -- neither triangle has less than two acute angles inside it -- the inside angles of each triangle add up to 180 degrees -- the outside angles of each triangle add up to 360 degrees -- neither triangle has any side parallel to any other side -- the area of each triangle is half of the product of its base and its height -- no side of either triangle is longer than the sum of its other two sides -- no side of either triangle is shorter than the difference of its other two sides
