[b][color=#ff0000][size=150][size=200]A congruent triangle means that one triangle shape can fit exactly over another using Turns, Flips and Slides[/size][/size][/color][/b]

[size=150][color=#0000ff]When two triangles are congruent they will have exactly [/color][b][color=#ff0000]the same side measures (all 3 sides),[/color][/b][color=#0000ff] and the [/color][b][color=#ff0000]same angle measures (all 3 angles).[/color][/b][color=#0000ff][br][br]The equal sides and angles may not be in the same position (if there is a turn of a flie), but they are there.[/color][/size]

[size=150][b][color=#980000][size=200]Same Sides[/size][/color][/b][/size]

[b][color=#0000ff]When the sides are the same then the triangles are congruent.[/color][/b]

[size=200][b][color=#980000]Same Angles[/color][/b][/size]

[size=150][b][color=#0000ff][size=200]Does this also work with angles? Not always![/size][/color][/b][/size]

[size=200][b][color=#ff0000]Marking[/color][/b][/size]

[b][color=#1e84cc][size=150]When two triangles are congruent we often mark corresponding sides and angles like this:[/size][/color][/b]

[size=150][b][color=#980000]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][/color][/b][/size][b][color=#980000][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.
