Can two triangles with 2 congruent angles and 1 congruent side congruent?
Yes, they are. IF the side is between the two angles in both triangles,and all three items flow in the same direction in both triangles.
Does a triangle and a line have equal 180?
If you took the three angles of a triangle and glued them on a piece of paper side by side the outer sides would make a straight line. A triangles three angles add up equal 180 degrees. A straight angle,line, equals 180 degrees.
Can three triangles be proved congruent together?
Yes if they have the same interior angles and have the same side lengths
How would you prove triangles are congruent?
You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.
How are the triangles the same?
-- 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
