What does congruent mean in math? In geometry, two figures are congruent when they have exactly the same shape and size. One figure can be moved, rotated, or flipped to match the other without resizing it. The symbol \u2245<\/strong> means \u201cis congruent to.\u201d<\/p>\n\n\n\n

In this guide, you will learn what congruent means, how congruent figures work, the five triangle congruence rules, why AAA and SSA do not prove congruence, how congruence differs from similarity, and how to solve common congruence problems.<\/p>\n\n\n\n

<\/span>What Does Congruent Mean in Math?<\/span><\/h2>\n\n\n\n

In math, congruent means exactly the same in size and shape<\/strong>.<\/p>\n\n\n\n

Two figures are congruent when all their corresponding measurements match. They can look different on the page, because one figure may be moved, turned, or flipped, but the measurements do not change.<\/p>\n\n\n\n

For example:<\/p>\n\n\n\n

    \n
  • Two line segments with the same length are congruent.<\/li>\n\n\n\n
  • Two angles with the same measure are congruent.<\/li>\n\n\n\n
  • Two circles with the same radius are congruent.<\/li>\n\n\n\n
  • Two triangles with the same corresponding side lengths and angle measures are congruent.<\/li>\n<\/ul>\n\n\n\n

    The notation is:<\/p>\n\n\n\n

    A \u2245 B<\/strong><\/p>\n\n\n\n

    This means \u201cA is congruent to B.\u201d<\/p>\n\n\n\n

    Before learning the formal rules, use the interactive model below. Move, rotate, or flip the second triangle. If you resize it, notice what happens to the congruence relationship.<\/p>\n\n\n\n\n\n
