Cov khoom ntawm Tangents

Cov tangent kab yeej tsis hla lub voj voog, nws tsuas yog kov lub voj voog xwb. Nyob rau ntawm qhov chaw ntawm tangency, nws yog perpendicular mus rau lub vojvoog. Ib chord thiab tangent tsim lub kaum sab xis thiab lub kaum sab xis no zoo ib yam li ntawm tangent sau nyob rau sab opposite ntawm lub chord.

Ntxiv mus, tangent kab theorem yog dab tsi?

A kab yog tangent mus rau ib lub voj voog yog tias thiab tsuas yog tias tus kab yog perpendicular rau lub vojvoog kos mus rau qhov chaw ntawm tangency. Ob Tangent Theorem . Ob- Tangent Theorem hais tias yog ob tangent ntu yog rub mus rau ib lub voj voog los ntawm tib lub ntsiab lus sab nraud, ces lawv yog congruent.

Tsis tas li ntawd, puas tangent txhais tau tias yog perpendicular? Los ntawm a perpendicular lis, we txhais tau tias ib txoj kab uas hla lwm kab hauv ib lub kaum sab xis. Ntawm qhov tod tes, a tangent yog ib txoj kab uas kov ib qho nkhaus ntawm ib qho chaw. Los ntawm a perpendicular lis, we txhais tau tias ib txoj kab uas hla lwm kab hauv ib lub kaum sab xis. Ntawm qhov tod tes, a tangent yog ib txoj kab uas kov ib qho nkhaus ntawm ib qho chaw.

Tom qab ntawd, txoj cai ntawm tangent yog dab tsi?

Cov cai ntawm tangent ( Law of Tan ) piav qhia txog qhov sib txawv ntawm qhov sib txawv thiab cov lej ntawm sab ntawm daim duab peb sab thiab tangents ntawm ib nrab ntawm qhov sib txawv thiab sum ntawm cov ces kaum sib xws. Nws sawv cev rau kev sib raug zoo ntawm cov tangent ntawm ob lub kaum sab xis ntawm ib daim duab peb sab thiab qhov ntev ntawm qhov opposite sab.

Koj txhais li cas los ntawm Tangent?

Hauv geometry, lub tangent kab (los yog yooj yim tangent ) mus rau lub dav hlau nkhaus ntawm qhov taw tes yog txoj kab ncaj nraim uas "tsuas yog kov" qhov nkhaus ntawm qhov taw tes. Leibniz txhais tias nws yog kab los ntawm ib khub ntawm infinitely kaw cov ntsiab lus ntawm qhov nkhaus. Lo lus " tangent "los ntawm Latin tangere, "touch".
