the sum of the angle sin one triangle is 180, so the sum in three triangles would be 180x3, which is 540 degrees.

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
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.
If two triangles have three pairs of congruent angles then the triangles are guaranteed to be congruent true or false?
False, because they could be similar triangles having the same angles but proportionally different side lengths

Which explains why AAA is not enough to prove two triangles congruent?
Two triangles with three congruent angles may have different side lengths.

If two triangles have three pairs of congruent angles the the triangle is congruent?
Yes they are. Or they could have three pairs of congruent sides, or they could have one pair of congruent angles and two pairs of sides. As far as a triangle goes, if you have at least three pairs of congruent sides or angles they are congruent. This answer is wrong. The triangles are only similar. For congruent trisngles we have the following theorems = Side - side - side, Side - Angle - side , Angle - angle - side, Right triangle - hypotenuse - side.
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
Are triangles congruent if so how do you know?
ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

What is angle side angle prostulate?
If 2 "corresponding" angles of two triangles and the side between the two angles are equal, then the two triangles are congruent. This means all their "corresponding" sides and angles are equal.
If the corresponding side lengths of two triangles are congruent the corresponding angles are also congruent.?
False. The statement should be: If the corresponding side lengths of two triangles are congruent, and the triangles are similar, then the corresponding angles are also congruent.
