A right angle is an internal angle equal to 90° This is a right angleSee that special symbol like a box in the corner? That says it is a right angle. The 90° is rarely written in. If we see the box in the corner, we are being told it is a right angle.All the angles ...
The sum of all 3 interior angles of a triangle is equal to 180°. Hence, 90° + 30° + x = 180°.Solve for xx = 180 – (90 + 30) = 60°.Practice Problems On Angles1 The sum of all angles around a point equals 360° 180° 270° 90° 2 Angles that sum up to 90° ...

Two angles are complementary if the sum of the angles is equal to 90º (ninety degrees). For example, an angle that is 30º and an angle that is 60º are two complementary angles.Since 90º is the measurement for a right angle, another way to tell if two angles are ...
Also many students demonstrated a relatively better understanding of the concept of triangle than that of quadrilaterals. Knowledge of class inclusions of shape was absent among these learners. The results of this study were found to be consistent with those of earlier studies and recommendations are...
