Figure 6: center of gravity of the triangle inscribed Investigate about the difference between UHF and VHF signal. Conduct an interview with a technician trying to discover the mechanism of operation of a radio station. Have you seen here, in this production, the points belonging to a circumference eqüidistam a point called the center of the circle. This center can be characterized as a balance? To answer this question, note the following drawing. We have a triangle inscribed in circumference. Was done the following: drew up two segments. One part of the point A toward point B, the latter, the midpoint of the segment DE. The other part of the point D and goes to point C, the midpoint of AE side of the triangle. The segments AB and CD intersect at point F, called the centroid or center of the triangle is called balance and center of gravity of the triangle. Also drew attention to three points belonging to the circle, namely, G, H and I. Segments GH and IH are strings circumference. Then built the bisector bisector of GH and IH. A mathematical definition says that any perpendicular bisector of a line passing through the center of a circle. This means that when you need to find the center of a circle, con- truo at least two bisectors in March and their intersection. The point of intersection of the bisectors is the center of the circle. The center of gravity of the triangle inscribed in Figure 5, coincides with the center of the circle. ACTIVITY Good question! In the case of Figure 5, we can say and prove that the center of the circle that circumscribes the triangle is also its center of gravity? () YES () NO. Justify. If you take a circular figure, find its center and place it on a fine point, she will remain suspended on account of relying on the object at its center point? Gather group with colleagues, make this experience and write response. What Mathematics is present in the rescue boat?

Slika 6: težište trokuta upisanom Dakle ... Istražiti o razlici između UHF i VHF signal. obavlja razgovor sa tehničar pokušava otkriti mehanizam rada radijske postaje. Jeste li vidjeli ovdje, u ovoj proizvodnji, točke koje pripadaju opsegom eqüidistam točku zove središte kruga. Ovaj centar se može okarakterizirati kao stanje? Za odgovor na ovo pitanje, imajte na umu sljedeće crtež. Imamo trokut upisan u obujmu. Je učinjeno sljedeće: izradila dva segmenta. Jedan dio točke A prema točki B, potonji, prema srednjem u segmentu DE. Drugi dio točki D i ide u točki C, duzine AE strani trokuta. Segmenti AB i CD sijeku u točki F, naziva težište ili središte trokuta zove ravnotežu i težište trokuta. Također je skrenuo pozornost na tri točke koje pripadaju krugu, naime, G, H i I. Segmenti GH i IH su nizovi opsega. Zatim je sagradio simetrala simetrala GH i IH. Matematička definicija kaže da je bilo simetralu od linije koja prolazi kroz središte kruga. To znači da kada je potrebno naći središte kruga, kon- truo najmanje dvije simetrale u ožujku i njihove raskrižje. Točka sjecištu simetrala dužina je središte kruga. Težište trokuta upisana na slici 5, podudara se s središtu kruga. AKTIVNOST Dobro pitanje! U slučaju slici 5, možemo reći i dokazati da je središte kruga koji ograničava trokut je i njegov centar gravitacije? () DA () NE. Opravdati. Ako se kružni lik, pronašli svoje središte i stavite ga na finu točku, ona će ostati suspendiran zbog oslanjanja na objekt u njenom središtu trenutku?
