You Can prove that radius to the point of contact of a tangent is perpendicular by Take two Iron Rings with a radius of a pin that you have like a stitching needle.. The iron rings should be at a thickness of 1 cm... Join the two rings by superimposing but not exactly‚ without gap. just leave a gap between the two circumference of the circle such that there is parallel gap throughout the two rings then join them at two points{one at any where and another at straight opp to the other} using m~seal

Oxygen (O) Human beings obtain this element from the air. It enters a person’s bloodstream through the lungs. The blood carries oxygen to the cells of the body. In the cells‚ oxygen combines with chemicals obtained from food. Energy produced during this process makes it possible for each cell to perform its function in the body. Also‚ oxygen atoms are present in water and water is essential to all life. It is present in many organic compounds. While oxygen is necessary for life‚ oxygen as ozone

APPLICATION OF SINE LAW The shorter diagonal of a parallelogram is 5.2 m. Find the perimeter of the parallelogram if the angles between the sides and the diagonal are 40o and 30o10’. From the top of a 150 m lighthouse‚ the angles of depression of two boats on the shore are 20o and 50o‚ respectively. If they are due north of the observation point‚ find the distance between them. SOLUTION Solved for a 150/sin50 = a/sin90 a = (150 sin90)/sin50

handicrafts. And one part of these shapes and angles is the angle bisector. Angle bisector is a ray that divides an angle into two congruent parts. It is also called the internal angle bisector. And the angle bisectors of a triangle intersect at a point called the incenter of triangle. This angle bisector is usually used or applied by the students in math particularly in the field of geometry. But unfortunately‚ there’s no device that can help the students bisect an angle easier. That’s one of the reasons

arcs. The shorter arc is called the minor arc. SPHERICAL TRIANGLES A spherical triangle is that part of the surface of a sphere bounded by three arcs of great circles. The bounding arcs are called the sides of the spherical triangle and the intersections of these arcs are called the vertices of the spherical triangle. The angle formed by two intersecting arcs is called a spherical angle. Like a plane triangle‚ the spherical triangle has also six parts – three angles and three sides. The sides

area of a hexagon using special right triangles‚ using trigonometry‚ breaking the hexagon into smaller polygons‚ and even show you how to construct one! So let’s get started‚ this hexagon has a radius of 6 cm‚ keep in mind that there are many different ways to do find the area of a hexagon. Use the formula 1/2asn meaning; ½ (apothem) (side length) (number of sides).You can put two radii (radii is a term for more than one radius) together and make a triangle. There is a problem we do not know the
