Proofs and congruent triangles ( serious full answers only or 1 star and report )
krok68 [10]

Answer:

<em>There are 5 ways to find if two triangles are congruent.</em>

<em>SSS-</em><em> {Side Side Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, each with the same measures on each 3 sides it deems the triangles congruent.</em>

<em>SAS- </em><em>{Side Angle Side Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 equal sides and one angle which is common among them; the triangles are congruent.</em>

<em>ASA- </em><em>{Angle Side Angle Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with 2 congruent angle measures and 1 congruent side; the triangles are indeed congruent.</em>

<em>AAS- </em><em>{Angle Angle Side Congruence.}</em>

<em>You may be wondering how this law of congruence differs from the previous one. </em><em> ASA </em><em>refers to any two angles and the included side, whereas </em><em>AAS </em><em>refers to the two corresponding angles and the non-included side.</em>

<em>HL- </em><em>{Hypotenuse Leg Congruence.}</em>

<em>This law of congruence states that if we have two triangles, with a common (congruent) leg and hypotenuse; the triangles are congruent.</em>
