Does the angle bisector of the vertex angle of an isosceles triangle divides the triangle into two congruent?

Only if the vertex angle being bisected is between the sides of equal length will the result be two congruent triangles.

How do you decompose a rectangle into congruent triangles?

Its diagonals divides it into two equal right angle triangles.

What is the angle bisector of a triangle?

It is a straight line which divides an interior angle of the triangle into two angles of equal measure.

Why are angles equal when sides are equal?

This is only true of triangles. Rhombi and other "squashed" polygons with more than three sides show that it is not true otherwise. The two equal sides meet at an angle. It can be shown that the bisector of that angle divides the triangle into two triangles with one set of equal sides, one common side and these sides define angles of equal measure. So by SAS, the two triangle are congruent and so the angles in question are equal. Alternatively, you could prove (as easily) that the altitude from that angle divides the original triangle into two right angled triangles with a common side and equal hypotenuses. Again congruence resulting in the equality of the angles as required.

Why are triangles not equilateral?

All sides on a triangle can be equal. If they are each angle will equal 60 degrees.

The triangles sum says that the 3 angle in a triangle always equal 180?

The three angles of a triangle are always equal to 180°, if not equal to 180° then it is not a triangle.

How is classifying a triangle as a right triangle different from classifying it as an equilateral triangle?

Right Triangles = 1 angle is 90 degrees Equilateral Triangles = Triangles with all three sides are equal in length

Are angles in an isoceles triangle equal?

Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.

List and describe the 5 ways triangles can be classified by their angle?

What are not congruence theorems?

I am guessing you are interested in triangles. Here are two false triangle congruence theorem conjectures.1, If the angles of one triangle are equal respectively to the angles of another triangle, the triangles are congruent. ( abbreviated AAA).2. If two sides and one angle of a triangle are equal respectively the two sides and one angle of another triangle, the triangles are congruent. (abbreviated SSA)Comment: Draw triangles with pairs of equal sides but in which the included angle between the equal sides is acute in one case and obtuse in the others.

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.
