The missing reason is the same for both steps 2 and 4. In the second step, the angle between the two sides must be congruent, whereas in step four, the missing reasoning is the vertical and alternate interior angles must be congruent. Hence, the a and b must be equal in measure. Finally, in the fourth step, the horizontal and vertical angles must be congruent, so that the a and b angles are not equal.
Now, the problem is that the angle VSU and TSU must have the same value or measure. These two angles are congruent, and the missing reason in the proof is that the measures must be the same. However, we don’t need to prove that the two angles are congruent. In fact, we do not need to prove the property of equal measures to prove the triangle angle sum theorem.
Secondly, the missing reason in the proof is the definition of the transitive property. A transitive property is a mathematical property that applies to any object, whether it is an animal or a human. For example, the angle of the triangle is congruent if it is 90 degrees, unless there is a difference between the two sides. Similarly, the angle of a square is congruent if it is 90°.
The missing reason is the definition of congruent angles. The definition of congruent angles states that when two angles are congruent, they retain the same angle. This is the missing reason in the triangle angle sum theorem. This is a very important proof in the maths field. Once you understand the definition of a congruent angle, you can apply the theory to other angles. The missing reason in the proof is the division property.
The proof of the transitive property is missing the definition of congruent angles. The definition of congruent angles states that the triangle angle sum is equal to all other angles. The proof of the transitive property is incomplete if the triangle angles are not congruent. If this is the case, then the angle sum theorem does not have any meaning. This is a fundamental mistake in mathematics.
Another missing reason in the proof is the definition of congruent angles. The definition of congruent angles is the key to the transitive property of right triangles. Clearly, congruent angles are those that have the same value and are congruent. In this case, the angle TSU and VSU are incongruent. The missing reason in the proof is the triangle angle sum theorem.
