3 interior, and 6 exterior, i believe. so 9 is the total.
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
If two angles and a non-included side of one triangle are congruent to the corresponding two angles and side of another triangle, the triangles are congruent by the Angle-Angle-Side (AAS) theorem. This theorem states that if two angles and a corresponding side of one triangle are equal to two angles and the corresponding side of another triangle, then the two triangles are congruent. Thus, the triangles will have the same shape and size.
No. Angles don't have anything called a side length. However, one can use trigonometry to compute the angles of a triangle based on the side lengths of the triangle (triangles do have side lengths).
It is not an axiom, but a theorem.
There are 3 angles in a triangle.
three
A triangle has only 1 right angle. It only has one side that can possibly be a right angle. The type of triangle varies.
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.
There are exactly 3 equal angles (of 60o) and three equal sides in any equilateral triangle.
There are 3 angles in a triangle
A triangle has 3 angles.
Every triangle has three sides and three 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 and the included side of one triangle are equal to the corresponding angles and side of another triangle, then the two triangles are congruent.
False
Either of the two angles of a triangle that has the base for a side.
