Every side of any triangle is a side of each of two angles. In fact, every side of every polygon is a side of each of two angles.
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.
If two angles in a triangle are congruent to two angles in another triangle, then the ______________ angles are also congruent.
two angles
ASA is not a triangle, it is a method of proving that two triangles are congruent. ASA refers to showing that if two angles and a side (Angle-Side-Angle) of one triangle are the same measures as the corresponding angles and side of another triangle, then the two triangles are congruent. Since the three angles sum to 180 degrees, if two of them in one triangle are equal to the corresponding angles in the second triangle, then the third set of angles must also be equal. Consequently, ASA is equivalent to AAS and SAA. That is NOT The case with two sides and an angle, where it must be the included angle that is equal.
Yes, they are.
It is not an axiom, but a theorem.
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.
If two angles and the side opposite one of them in one triangle are equal to one side and two similarly located angles in a second triangle then the two triangles are congruent. (The triangles are exactly the same shape and size as each other).
Either of the two angles of a triangle that has the base for a side.
How many sides of each triangle and how many angles of each triangle do you have ? If you have two sides and the angle between them, or two angles and the side between them, equal to the same parts of the other triangle, then your triangles are congruent. You don't even have to know what the actual numbers are. If the expressions are equal, then the sides or angles are equal.
In a isosceles triangle, all angles are less than 90 degrees and therefore they are acute angles. Two angles on the opposite side of each other are equal angles.
An isosceles triangle has two equal side and angle measurements.
-- 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
Yes. What about them?
