[size=200][b][color=#0000ff]Congruent Triangles[/color][/b][/size]

[size=150]When two triangles are congruent they will have exactly [color=#ff7700][b]the same side measures (all 3 sides),[/b] and the [b]same angle measures (all 3 angles).[/b][/color]The equal sides and angles may not be in the same position, but they are there.[/size]

[size=150][b][size=200][color=#0000ff]Same Sides[/color][/size][/b][/size]

[b]When the sides are the same then the triangles are congruent.[/b]

[size=200][b][color=#0000ff]Same Angles[/color][/b][/size]

[size=150][b][size=200][color=#ff7700]Does this also work with angles? Not always![/color][/size][/b][/size]

[size=200][b][color=#0000ff]Marking[/color][/b][/size]

[b][size=150]When two triangles are congruent we often mark corresponding sides and angles like this:[/size][/b]

[size=150][b]The sides marked with one line are equal in length. Similarly for the sides marked with two lines. Also for the sides marked with three lines. [br][br][/b][/size][b][size=150]The angles marked with one arc are equal in size. Similarly for the angles marked with two arcs. Also for the angles marked with three arc. [/size][/b]
