In this video, we are going to learn about making a mobile stand using geometry. A point is an exact position or location on a plane surface. 2 or more points, when joined together, form a line. When two dots are joined together it forms a line segment. When two lines are placed at a distance of 90 degrees, it is called a right angle. Angles less than 90 degrees are called acute angle and angles above 90 degrees but below 180 degrees is called obtuse angle. If an angle looks like a straight line with 180 degrees, it is called a straight angle. When adding two angles, if the sum is exactly 90 degrees, it is called a complementary angle. When adding two angles, if the sum is exact 180 degrees, it is called a supplementary angle.
