The converse is ... An angle of a parallelogram is 20 degree less then its adjacent angle. In Euclidean geometry, the two acute angles in a right triangle are complementary, because the sum of internal angles of a triangle is 180 degrees, and the right angle itself accounts for 90 degrees. 0 0. If one angle is 80 degree, the measure of other angle is —————-A. 12. Two obtuse angles form a linear pair. If two angles are right angles, then they are congruent. I'm so confused :( 1. 1 decade ago. Vertical Angles: Two non adjacent angles formed by two intersecting lines. If two angles share a vertex and a side, then they are adjacent. As long as they add up to 90° they will be known as complementary angles. That is the next proposition. What has exactly two adjacent right angles that is not a parallelogram? If two of the angles have a common vertex and share a common side they are called adjacent angles. Then since they are supplementary, m∠A + m∠B = 180° And since they are congruent, m∠A = m∠B Substituting equals for equals in m∠A + m∠B = 180° m∠B + m∠B = 180° 2m∠B = 180° Divings both sides by 2 m∠B = 90° So ∠B is a right angle And since m∠B = m∠A m∠A = 90° So ∠B is a right angle So it's true that they are both right angles.
