Cov SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm qhov daim duab peb sab thiab suav nrog lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces tus ob daim duab peb sab yog zoo sib xws . A zoo sib xws transformation yog ib los yog ntau nruj transformations tom qab dilation.

Ua li no, koj ua li cas qhia tias ob daim duab peb sab zoo sib xws?

AA (Angle-Angle) Yog ob khub ntawm cov ces kaum nyob rau hauv ib khub ntawm daim duab peb sab yog congruent, ces cov daim duab peb sab zoo ib yam . Peb paub qhov no vim yog ob kaum khub yog tib yam, ces tus thib peb khub kuj yuav tsum sib npaug. Thaum peb lub kaum sab xis yog txhua qhov sib npaug, peb khub ntawm sab yuav tsum tau sib npaug.

Ib yam li ntawd, koj tuaj yeem qhia tau li cas yog tias daim duab peb sab sib haum? Ob triangles yog congruent yog tias lawv muaj: raws nraim tib yam peb sab thiab. raws nraim tib lub kaum sab xis.

Muaj tsib txoj hauv kev los nrhiav yog tias ob daim duab peb sab sib dhos: SSS, SAS, ASA, AAS thiab HL.

  1. SSS (sab, sab, sab)
  2. SAS (sab, kaum sab xis, sab)
  3. ASA (lub kaum sab xis, sab, kaum sab xis)
  4. AAS (lub kaum sab xis, sab, sab)
  5. HL (hypotenuse, ceg)

Ib tug kuj yuav nug, koj xav tau dab tsi los qhia koj puas ua pov thawj ob daim duab peb sab zoo sib xws los ntawm SAS zoo sib xws theorem?

Koj yuav tsum tau qhia uas ob sab ntawm ib daim duab peb sab yog proportional rau ob sib thooj sab ntawm lwm tus daim duab peb sab , nrog rau cov ces kaum sib raug zoo.

Puas yog cov kab sib txuas sib txuas?

Yog ob kab sib npaug yog txiav los ntawm ib tug transversal, cov ces kaum sib raug kev sib haum xeeb . Yog ob kab yog txiav los ntawm ib tug transversal thiab cov ces kaum sib raug kev sib haum xeeb , cov kab yog parallel . Sab hauv Angles ntawm Tib Sab ntawm Transversal: Lub npe yog ib qho kev piav qhia ntawm "qhov chaw" ntawm cov ces kaum no.
