5. Write the assumption you would make to start an indirect proof of the statement: ΔMNO is an equilateral triangle.
Examine the answer choices. The only value that does not satisfy the compound inequality is 13 since 13 is greater than 12.4. Thus, the answer is choice D.
are right angles.2. 2. Perpendicular lines form right
angles.3. 3. All right angles are congruent.4. 4. Definition of congruent angles
7. 7. If an angle of a triangle is greater than a second angle, then the side opposite the greater angle is longer than the side opposite the lesser angle.
