relationship between triangles and circles. Be sure to include a description of the different centers a triangle can have. Answer: Angles and points on the circumference of a circle are the same thing. A point on the unit circle is the same as a right triangle formed by a radius to the point and its perpendicular to the x-axis. Hence sines and cosines which come from ratios of legs of a right triangle to the length of the hypotenuse are also the coordinates of the point on a circle of radius one. (5

one person will stand in the middle blindfolded while the rest of the group circles around the blindfolded person. The blindfolded person represents ‘the willow.’ The rest of the group will form a tight circle and the blindfolded person will completely lean forward‚ it is important the surrounding circle catches the person and pushes them back up repeating the process again. The blindfolded person’s trust in the circle is key in this activity. Once all trust is gained the person that’s blindfolded

because the bigger the string‚ the greater the distance the pendulum needs to travel and so the more time it will take. This will occur because the string is like the radius of the circle and so changing the length of string will change the circumference of the circle‚ so the longer the piece of string; the bigger the circle‚ and the bigger the distance that the pendulum will travel. Equipment List: - string (180 cm) – to be tied to the weight to make the pendulum - small weight (50g) –

Time Frame: 45 min Prior to this lesson the students had a lesson on attributes. The children defined and identified attributes in different two-dimensional shapes. MA Framework Standard: Geometry K.G Identify and describe shapes (squares‚ circles‚ triangles‚ rectangles‚ hexagons‚ cubes‚ cones‚ cylinders‚ and spheres). 2. Correctly name shapes regardless of their orientations or overall size. Identify shapes as two-dimensional (lying in a plane‚ “flat”) or three-dimensional (“solid”).

In the poem "A Valediction: Forbidding Mourning"‚ by John Donne‚ the speaker is consoling his lover who is mournful of the speaker’s imminent departure. The speaker is saying that since they have stronger than ordinary love for one another‚ their love will endure the separation. Donne uses metaphysical conceits and comparative imagery to illustrate the crux of the poem. The speaker is reassuring his lover by reminding her of how great their love is; it transcends the physical and therefore will overcome

45 degree angle. Now the question arises of how he has derived this particular degree angle. The magic is the octave based system. The circle is the answer for everything in life. Take a small or big circle it has 360 degrees. Mr. Gann said that divide the circle by octave and you will get 45 degree angle. Here we are trying to connect the octave based circle with the natural year based on octave. Because from various writings Mr. Gann has said that 45 degree is important and the solstices are

Gregory‚ and the Bible. The first proof I will be talking about is Liu Hui’s. Liu Hui was a Chinese mathematician whose method for proving pi was to find the area of a polygon inscribed in a circle. When the number of sides on the inscribed polygon increased‚ its area became closer to the circumference of a circle and pi. For finding the side length of an inscribed polygon Liu Hui used a simple formula. (13Ma3) To find the side length of an inscribed polygon of 2n sides‚ if the side length of a polygon
