The angle in the middle is being shared by the two in the sides. When you have 3 angles and the first and the second angles are supplementary (the two together = 180 degrees) and the second and third angles are supplementary too the first and third angles will be congruent. It can also count as the bigger rectangles.Īll of the angles in this picture are also congruent because they are all right angles and we know this because they form 2 straight lines when they are separated. Right Angle Congruence Theorem: This theorem states that:Īll Right Angles are congruent to each other.Īll of the angles inside this kite are right angles making all of them 90º and making all of them congruent to each other.Īll of the little angles inside the white parts of the windows are congruent to each other because they all make a right angle.
